Reducing radicality in fertility-sparing surgery is associated with improved in vitro fertilization outcome in early-stage cervical cancer: A national retrospective study.

OBJECTIVE: Fertility-sparing surgery (FSS) aims to achieve oncological outcomes that are non-inferior to radical treatment while preserving fertility and optimizing reproductive results. This study assesses in vitro fertilization (IVF) outcomes in early-stage cervical cancer survivors following FSS, comparing radical and non-radical approaches. METHODS: This retrospective analysis used data from Hungary's National Health Insurance Fund (2004-2022) on patients who underwent IVF treatment following FSS for early-stage cervical cancer at ten Hungarian fertility clinics. Patients were classified into radical and non-radical surgical groups, with the uterine arteries being spared in the non-radical procedures. RStudio (R software version: 4.2.2) was used for statistical analysis. Student's t-test was used to compare group means, and Fisher's exact test was applied to assess independence and distributions between categorical variables, and to estimate odds. RESULTS: The study analyzed data from 122 IVF treatment cycles involving 36 patients. The non-radical group had a significantly higher live birth rate (83%, 5/6 compared to the radical group (17%, 5/30). Additionally, the non-radical group had a significantly higher implantation rate and cumulative live birth rate per oocyte retrieval (37%, 7/19 and 55%, 6/11 respectively) compared to the radical group (8%, 12/148 and 6%, 5/80 respectively). CONCLUSION: This is the largest study to evaluate IVF outcomes in young cervical cancer survivors who have undergone FSS. The findings suggest that less radical procedures are associated with significantly better IVF outcomes. These results emphasize the importance of considering oncological safety and reproductive outcomes together when choosing FSS for early-stage cervical cancer patients. It also highlights the reproductive benefits of performing less radical surgery.

Current treatment of pT1 rectal cancers in Denmark: A retrospective national cohort study.

AIM: Organ preservation strategies for patients with rectal cancer are increasingly common. In appropriately selected patients, local excision (LE) of pT1 cancers can reduce morbidity without compromising cancer-related outcomes. However, determining the need for completion surgery after LE can be challenging, and it is unknown if prior LE compromises subsequent total mesorectal excision (TME). The aim of this study is to describe the current management of patients with pT1 rectal cancers. METHOD: This is a retrospective national cohort study of the Danish Colorectal Cancer Group database, including patients with newly diagnosed pT1 cancers between 2016 and 2020. Patients were stratified according to treatment into LE alone, completion TME after LE or upfront TME. The treatment and outcomes of these groups were compared. RESULTS: A total of 1056 patients were included. Initial LE was performed in 715 patients (67.7%), of whom 194 underwent completion TME (27.1%). The remaining 341 patients underwent upfront TME (32.3%). Patients undergoing LE alone were more likely to be male with low rectal cancers and greater comorbidity. No differences in specimen quality or perioperative outcomes were noted between patients undergoing completion or upfront TME. Eighty-five patients (15.9%) had lymph node metastases (LNM). Pathological risk factors poorly discriminated between patients with and without LNM, with similar rates seen in patients with zero (14.1%), one (12.0%) or two (14.4%) risk factors. CONCLUSION: LE is a key component of the treatment of pT1 rectal cancer and does not appear to affect the outcomes of completion TME. Patient selection for completion TME remains a major challenge, with current stratification methods appearing to be inadequate.

Comparative evaluation of reproductive organ-preserving versus standard radical cystectomy in female: a meta-analysis and systematic review of perioperative, oncological, and functional outcomes.

BACKGROUND: To evaluate the perioperative, oncological, and functional outcomes of reproductive organ-preserving radical cystectomy (ROPRC) compared to standard radical cystectomy (SRC) in the treatment of female bladder cancer. METHODS: A systematic search was conducted in November 2023 across several scientific databases. We executed a systematic review and cumulative meta-analysis of the primary outcomes of interest, adhering to the PRISMA and AMSTAR guidelines. The study was registered in PROSPERO (CRD42024501522). RESULTS: The meta-analysis included 10 studies with a total of 2015 participants. ROPRC showed a significant reduction in operative time and postoperative fasting period compared to SRC (MD - 45.69, 95% CI - 78.91 ~ - 12.47, p = 0.007, and MD - 0.69, 95% CI - 1.25 ~ - 0.13, p = 0.02, respectively). Functional outcomes, both daytime continence rate (OR 4.94, 95% CI 1.53 ~ 15.91, p = 0.008) and nighttime continence rate (OR 5.91, 95% CI 1.94 ~ 18.01, p = 0.002), and sexual function measured by the Female Sexual Function Index (MD 5.72, 95% CI 0.19 ~ 11.26, p = 0.04), were significantly improved in the ROPRC group. There were no significant differences between ROPRC and SRC in terms of estimated blood loss, length of hospital stay, overall postoperative complications, minor complications or major complications. Oncologically, both procedures showed comparable outcomes with no significant differences in positive surgical margins, tumor recurrence rates, overall survival, cancer-specific survival, recurrence-free survival, or progression-free survival. CONCLUSIONS: ROPRC is a viable and effective alternative to SRC in female bladder cancer patients, offering enhanced functional outcomes and similar oncological safety. These findings suggest that ROPRC can improve the quality of life in female bladder cancer patients without compromising the efficacy of cancer treatment.

Pelvic organ-preserving radical cystectomy versus standard radical cystectomy in female patients diagnosed with bladder cancer.

BACKGROUND: Pelvic organ-preserving radical cystectomy (POPRC) has been reported to result in a better postoperative quality of life in female with bladder cancer compared to standard radical cystectomy (SRC). However, its oncological outcomes remain a concern. PATIENTS AND METHODS: Female patients with bladder cancer who underwent POPRC or SRC were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Logistic regression was used to identify predictors of POPRC usage. To avoid the potential impact of baseline differences between groups on survival, a 1:2 propensity score matching (PSM) was implemented. After that, Kaplan-Meier curves and Log-rank tests were used to determine the significance of overall survival (OS) differences between patients in the SRC group and POPRC group. Finally, subgroup analysis based on predetermined indicators was performed. RESULTS: A total of 2193 patients were included with a median follow-up of 53 months, of whom 233 (10.6%) received POPRC and 1960 (89.4%) received SRC. No definitive predictors of POPRC were identified. Before PSM, POPRC resulted in comparable OS to SRC (HR = 1.09, p = 0.309), while after PSM, POPRC was associated with significantly worse OS (HR = 1.23, p = 0.038). In subgroup analyses, POPRC led to non-inferior OS (HR = 1.18, 95%CI 0.71-1.95, p = 0.531) in patients with non-muscle invasive bladder cancer (NMIBC) and T2 patients (HR = 1.07, p = 0.669), but significantly worse OS in T3 patients (HR = 1.41, p = 0.02). CONCLUSION: Currently, patients undergoing POPRC have not undergone strict screening, and candidates for POPRC should have more stringent criteria in the future to achieve satisfactory oncological outcomes. However, flaws in the study make more evidence needed to support our findings.

Impact of resection margin on outcome in soft-tissue sarcomas of the extremities treated with limb-sparing surgery and postoperative radiotherapy.

BACKGROUND: The standard curative treatments for extremity soft tissue sarcoma (ESTS) include surgical resection with negative margins and perioperative radiotherapy. However, the optimal resection margin remains controversial. This study aimed to evaluate the outcomes in ESTS between microscopically positive margin (R1) and microscopically negative margin (R0) according to the Union for International Cancer Control (UICC) (R + 1 mm) classification. METHODS: Medical records of patients with localized ESTS who underwent primary limb-sparing surgery and postoperative radiotherapy between 2004 and 2015 were retrospectively reviewed. Patients were followed for at least 5 years or till local or distant recurrence was diagnosed during follow-up. Outcomes were local and distal recurrences and survival. RESULTS: A total of 52 patients were included in this study, in which 17 underwent R0 resection and 35 underwent R1 resection. No significant differences were observed in rates of local recurrence (11.4% vs. 35.3%, p = 0.062) or distant recurrence (40.0% vs. 41.18%, p = 0.935) between R0 and R1 groups. Multivariate analysis showed that distant recurrences was associated with a Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC) grade (Grade III vs. I, adjusted hazard ratio (aHR): 12.53, 95% confidence interval (CI): 2.67-58.88, p = 0.001) and tumor location (lower vs. upper extremity, aHR: 0.23, 95% CI: 0.07-0.7, p = 0.01). Kaplan-Meier plots showed no significant differences in local (p = 0.444) or distant recurrent-free survival (p = 0.161) between R0 and R1 groups. CONCLUSIONS: R1 margins, when complemented by radiotherapy, did not significantly alter outcomes of ESTS as R0 margins. Further studies with more histopathological types and larger cohorts are necessary to highlight the path forward.

Phallus preservation and reconstruction: 5-year outcomes of national penile cancer centralisation in the Republic of Ireland.

INTRODUCTION: Penile cancer is a rare urological malignancy with an age-standardised incidence of 0.8 per 100,000 person-years [1]. Given this low incidence it has been suggested that centralised care may improve patient outcomes in relation to phallus sparing surgery and nodal assessment [2]. We aim to assess the outcomes after 5-years of national centralisation of penile cancer care. METHODS: A retrospective analysis of prospectively collected data was performed. All patients undergoing penile cancer surgery from January 2018 to December 2022 following centralisation of care were included. The primary outcome was proportion of phallus sparing procedures performed. Secondary outcomes were patient characteristics, histologic outcomes and procedures performed. RESULTS: 124 patients underwent surgery in the study period. Mean age was 64.49 (±13.87). Overall, 82.3% of patients underwent phallus sparing surgery. This remained stable over the 5-year period from 2018 to 2022 â€‹at 92%, 85%, 76%, 79% and 78% respectively (p â€‹= â€‹0.534). 62.7% had reconstruction performed, including split-thickness skin graft neoglans formation, (57.8% [n â€‹= â€‹37]), preputial flap (32.8% [n â€‹= â€‹21]), glans resurfacing (4.7% [n â€‹= â€‹3]), shaft advancement flap (1.6% [n â€‹= â€‹1]), penile shaft skin graft (1.6% [n â€‹= â€‹1]), and partial penectomy with urethral centralisation (1.6% [n â€‹= â€‹1]). Phallus preservation was not affected by positive nodal status (OR 0.75 [95% CI 0.249-2.266], p â€‹= â€‹0.564) or T-stage ≥1b (OR 0.51 [95% CI 0.153-1.711], p â€‹= â€‹0.276). There has been a significant reduction in Nx nodal status from 64% in 2017 to 15% in 2021 (p â€‹= â€‹0.009). CONCLUSION: Centralisation of treatment for rare malignancies such as penile cancer may improve oncologic outcomes and rates of phallus preservation. This study has shown centralisation to has a high rate of phallus preservation. Further long-term analysis of outcomes in Ireland is required.

Local excision vs. proctectomy in patients with ypT0-1 rectal cancer following neoadjuvant therapy: a propensity score matched analysis of the National Cancer Database.

BACKGROUND: We aimed to evaluate outcomes of organ preservation by local excision (LE) compared to proctectomy following neoadjuvant therapy for rectal cancer. METHODS: This retrospective observational study using the National Cancer Database (NCDB) included patients with locally advanced non-metastatic rectal cancer (ypT0-1 tumors) treated with neoadjuvant therapy between 2004 and 2019. Outcomes of patients who underwent LE or proctectomy were compared. 1:1 propensity score matching including patient demographics, clinical and therapeutic factors was used to minimize selection bias. Main outcome was overall survival (OS). RESULTS: 11,256 of 318,548 patients were included, 526 (4.6%) of whom underwent LE. After matching, mean 5-year OS was similar between the groups (54.1 vs. 54.2 months; p = 0.881). Positive resection margins (1.2% vs. 0.6%; p = 0.45), pathologic T stage (p = 0.07), 30-day mortality (0.6% vs. 0.6%; p = 1), and 90-day mortality (1.5% vs. 1.2%; p = 0.75) were comparable between the groups. Length of stay (1 vs. 6 days; p < 0.001) and 30-day readmission rate (5.3% vs. 10.3%; p = 0.02) were lower in LE patients. Multivariate analysis of predictors of OS demonstrated male sex (HR 1.38, 95% CI 1.08-1.77; p = 0.009), higher Charlson score (HR 1.52, 95% CI 1.29-1.79; p < 0.001), poorly differentiated carcinoma (HR 1.61, 95% CI 1.08-2.39; p = 0.02), mucinous carcinoma (HR 3.53, 95% CI 1.72-7.24; p < 0.001), and pathological T1 (HR 1.45, 95% CI 1.14-1.84; p = 0.002) were independent predictors of increased mortality. LE did not correlate with worse OS (HR 0.91, 95% CI 0.42-1.97; p = 0.82). CONCLUSION: Our findings show no overall significant survival difference between LE and total mesorectal excision, including ypT1 tumors. Moreover, patients with poorly differentiated or mucinous adenocarcinomas generally had poorer outcomes, regardless of surgical method.

Cumulative Incidence and Risk Factors of Permanent Stoma After Intersphincteric Resection for Ultralow Rectal Cancer.

BACKGROUND: A permanent stoma is an unintended consequence that cannot be avoided completely after intersphincteric resection for ultralow rectal cancer. Unfortunately, its incidence and risk factors have been poorly defined. OBJECTIVE: The objective was to determine the cumulative incidence and risk factors of permanent stoma after intersphincteric resection for ultralow rectal cancer. DESIGN: This study was a retrospective analysis of prospectively collected data. SETTINGS: This study was conducted at a colorectal surgery referral center. PATIENTS: A total of 185 consecutive patients who underwent intersphincteric resection with diverting ileostomy from 2011 to 2019 were included. MAIN OUTCOME MEASURES: The primary outcome was the incidence of and risk factors for the permanent stoma. The secondary outcome included differences in stoma formation between patients with partial, subtotal, and total intersphincteric resection. RESULTS: After a median follow-up of 40 months (range, 6-107 months), 26 of 185 patients eventually required a permanent stoma, accounting for a 5-year cumulative incidence of 17.4%. The causes of permanent stoma were anastomotic morbidity (46.2%, 12/26), local recurrence (19.2%, 5/26), distant metastasis (19.2%, 5/26), fecal incontinence (3.8%, 1/26), perioperative mortality (3.8%, 1/26), patients' refusal (3.8%, 1/26), and poor general condition (3.8%, 1/26). Although the incidence of permanent stoma was significantly different between the intersphincteric resection groups (partial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), it was not an independent predictor of stoma formation. Multivariate analysis demonstrated that anastomotic leakage (OR = 5.29; p = 0.001) and anastomotic stricture (OR = 5.13; p = 0.002) were independently predictive of permanent stoma. LIMITATIONS: This study was limited by its retrospective nature and single-center data. CONCLUSIONS: The 5-year cumulative incidence of permanent stoma was 17.4%. Anastomotic complications were identified as risk factors. Patients should be informed of the risks and benefits when contemplating the ultimate sphincter-sparing surgery. It might be preferable to decrease the probability of permanent stoma by further minimizing anastomotic complications. See Video Abstract at http://links.lww.com/DCR/B704. INCIDENCIA ACUMULADA Y FACTORES DE RIESGO DE ESTOMA PERMANENTE DESPUS DE UNA RESECCIN INTERESFNTRICA EN CNCER RECTAL ULTRA BAJO: ANTECEDENTES:La necesidad de efectuar un estoma permanente es la consecuencia no intencional e inevitable por completo después de una resección interesfintérica en presencia de un cáncer rectal ultra bajo. Desafortunadamente, la incidencia y los factores de riesgo se han definido en una forma limitada.OBJETIVO:El objetivo fue determinar la incidencia acumulada y los factores de riesgo para la necesidad de efectuar un estoma permanente después de la resección intersfintérica de un cáncer rectal ultra bajo.DISEÑO:El presente estudio es un análisis retrospectivo de la información obtenida.ESCENARIO:Centro de referencia de cirugía colo-rectal.PACIENTES:Se incluyeron un total de 185 pacientes consecutivos que se sometieron a resección intersfintérica de un cáncer rectal ultra bajo con ileostomía de derivación de 2011 a 2019.MEDICION DE RESULTADOS:El resultado principal fue la identificación de la incidencia y los factores de riesgo para la presencia de un estoma permanente. En forma secundaria se describieron los resultados de las diferentes técnicas de la formación de un estoma entre los pacientes con resección interesfintérica parcial, subtotal o total.RESULTADOS:Posterior a una media de seguimiento de cuarenta meses (rango de 6 a 107), 26 de 185 pacientes requirieron en forma eventual un estoma permanente, lo que equivale a una incidencia acumulada a cinco años de 17.4 %. Las causas para dejar un estoma permanente fueron morbilidad de la anastomosis (46.2%, 12/26), recurrencia local (19.2%, 5/26), metástasis a distancia (19.2%, 5/26), incontinencia fecal (3.8%, 1/26), mortalidad perioperatoria (3.8%, 1/26), rechazo del paciente (3.8%, 1/26), y malas condiciones generales (3.8%, 1/26). Aunque la incidencia de un estoma permanente fue significativamente diferente entre los grupos de resección interesfintérica (parcial vs subtotal vs total: 8.3% vs 20% vs 25.8%, p = 0.02), no se consideró un factor predictor independiente para la formación de estoma. En el análisis multivariado se demostró que la fuga anatomótica (OR = 5.29; p = 0.001) y la estenosis anastomótica (OR = 5.13; p = 0.002) fueron factores independientes para predecir la necesidad de un estoma permanente.LIMITACIONES:La naturaleza retrospectiva del estudio y la información proveniente de un solo centro.CONCLUSIONES:La incidencia acumulada a cinco años de estoma permantente fue de 17.4%. Se consideran a las complicaciones anastomóticas como factores de riesgo. Los pacientes deberán ser informados de los riesgos y beneficios cuando se considere la posibilidad de efectuar una cirugía preservadora de esfínteres finalmente. Puede ser preferible disminuir la probabilidad de dejar un estoma permanente tratando de minimizar la posibilidad de complicaciones de la anastomosis.

Outcomes of Patients With Local Regrowth After Nonoperative Management of Rectal Cancer After Neoadjuvant Chemoradiotherapy.

BACKGROUND: Clinical complete responders after chemoradiation for rectal cancer are increasingly being managed by a watch-and-wait strategy. Nonetheless, a significant proportion will experience a local regrowth, and the long-term oncological outcomes of these patients is not totally known. OBJECTIVE: The purpose of this study was to analyze the outcomes of patients who submitted to a watch-and-wait strategy and developed a local regrowth, and to compare these results with sustained complete clinical responders. DESIGN: This was a retrospective study. SETTING: Single institution, tertiary cancer center involved in alternatives to organ preservation. PATIENTS: Patients with a biopsy-proven rectal adenocarcinoma (stage II/III or low lying cT2N0M0 at risk for an abdominoperineal resection) treated with chemoradiation who were found at restage to have a clinical complete response. INTERVENTIONS: Rectal cancer patients treated with chemoradiation who underwent a watch-and-wait strategy (without a full thickness local excision) and developed a local regrowth were compared to the remaining patients of the watch-and-wait strategy. MAIN OUTCOME MEASURES: Overall survival between groups, incidence of regrowth' and results of salvage surgery. RESULTS: There were 67 patients. Local regrowth occurred in 20 (29.9%) patients treated with a watch-and-wait strategy. Mean follow-up was 62.7 months. Regrowth occurred at mean 14.2 months after chemoradiation, half of them within the first 12 months. Patients presented with comparable initial staging, lateral pelvic lymph-node metastasis, and extramural venous invasion. The regrowth group had a statistically nonsignificant higher incidence of mesorectal fascia involvement (35.0% vs 13.3%, p = 0.089). All regrowths underwent salvage surgery, mostly (75%) a sphincter-sparing procedure. 5-year overall survival was 71.1% in patients with regrowth and 91.1% in patients with a sustained complete clinical response (p = 0.027). LIMITATIONS: This study was limited by its retrospective evaluation of patient selection for a watch-and-wait strategy and outcomes, as well as its small sample size. CONCLUSIONS: Local regrowth is a frequent event when following a watch-and-wait policy (29.9%); however, patients could undergo salvage surgical treatment with adequate pelvic control. In this series, overall survival showed a statistically significant difference from patients managed with a watch-and-wait strategy who experienced a local regrowth compared to those who did not.

No obstante, una proporción significativa experimentará un rebrote local y los resultados oncológicos a largo plazo de estos pacientes, no se conocen por completo.OBJETIVO:El propósito de este estudio, fue analizar los resultados de los pacientes sometidos a una estrategia de observación y espera, que desarrollaron un rebrote local, y comparar estos resultados con respondedores clínicos completos sostenidos.DISEÑO:Este fue un estudio retrospectivo.ENTORNO CLINICO.Institución única, centro oncológico terciario involucrado en alternativas a la preservación de órganos.PACIENTES:Pacientes con un adenocarcinoma de recto comprobado por biopsia (estadio II / III o posición baja cT2N0M0, en riesgo de resección abdominoperineal), tratados con quimiorradiación, y que durante un reestadiaje, presentaron una respuesta clínica completa.INTERVENCIONES:Los pacientes con cáncer de recto tratados con quimiorradiación, sometidos a una estrategia de observación y espera (sin una escisión local de espesor total) y que desarrollaron un rebrote local, se compararon con los pacientes restantes de la estrategia de observación y espera.PRINCIPALES MEDIDAS DE VALORACION:Supervivencia global entre los grupos, incidencia de rebrote y resultados de la cirugía de rescate.RESULTADOS:Fueron 67 pacientes. El rebrote local ocurrió en 20 (29,9%) pacientes tratados con una estrategia de observación y espera. El seguimiento medio fue de 62,7 meses. El rebrote se produjo a la media de 14,2 meses después de la quimiorradiación, la mitad de ellos dentro de los primeros 12 meses. Los pacientes se presentaron con una estadificación inicial comparable, metástasis en los ganglios linfáticos pélvicos laterales e invasión venosa extramural. El grupo de rebrote tuvo una mayor incidencia estadísticamente no significativa de afectación de la fascia mesorrectal (35,0 vs 13,3%, p = 0,089). Todos los rebrotes se sometieron a cirugía de rescate, en su mayoría (75%) con procedimiento de preservación del esfínter. La supervivencia global a 5 años fue del 71,1% en pacientes con rebrote y del 91,1% en pacientes con una respuesta clínica completa sostenida (p = 0,027).LIMITACIONES:Evaluación retrospectiva de la selección de pacientes para una estrategia y resultados de observar y esperar, tamaño de muestra pequeño.CONCLUSIONES:El rebrote local es un evento frecuente después de la política de observación y espera (29,9%), sin embargo los pacientes podrían someterse a un tratamiento quirúrgico de rescate con un adecuado control pélvico. En esta serie, la supervivencia global mostró una diferencia estadísticamente significativa de los pacientes manejados con una estrategia de observación y espera que experimentaron un rebrote local, en comparación con los que no lo hicieron.

Comparative Outcomes of Salvage Retzius-Sparing versus Standard Robotic Prostatectomy: An International, Multi-Surgeon Series.

PURPOSE: Salvage radical prostatectomy is rare due to the risk of postoperative complications. We compare salvage Retzius-sparing robotic assisted radical prostatectomy (SRS-RARP) with salvage standard robotic assisted radical prostatectomy (SS-RARP). MATERIALS AND METHODS: A total of 72 patients across 9 centers were identified (40 SRS-RARP vs 32 SS-RARP). Demographics, perioperative data, and pathological and functional outcomes were compared using Student's t-test and ANOVA. Cox proportional hazard models and Kaplan-Meier curves were constructed to assess risk of incontinence and time to continence. Linear regression models were constructed to investigate postoperative pad use and console time. RESULTS: Median followup was 23 vs 36 months for SRS-RARP vs SS-RARP. Console time and estimated blood loss favored SRS-RARP. There were no differences in complication rates or oncologic outcomes. SRS-RARP had improved continence (78.4% vs 43.8%, p <0.001 for 0-1 pad, 54.1% vs 6.3%, p <0.001 for 0 pad), lower pads per day (0.57 vs 2.03, p <0.001), and earlier return to continence (median 47 vs 180 days, p=0.008). SRS-RARP was associated with decreased incontinence defined as >0-1 pad (HR 0.28, 95% CI 0.10-0.79, p=0.016), although not when defined as >0 pad (HR 0.56, 95% CI 0.31-1.01, p=0.053). On adjusted analysis SRS-RARP was associated with decreased pads per day. Lymph node dissection and primary treatment with stereotactic body radiation therapy were associated with longer console time. CONCLUSIONS: SRS-RARP is a feasible salvage option with significantly improved urinary function outcomes. This may warrant increased utilization of SRS-RARP to manage men who fail nonsurgical primary treatment for prostate cancer.

IVF impact on the risk of recurrence of endometrial adenocarcinoma after fertility-sparing management.

RESEARCH QUESTION: Do IVF treatments after conservative management of endometrial atypical hyperplasia or grade 1 endometrial adenocarcinoma (AH/EC) increase the risk of disease recurrence? DESIGN: This is a prospective cohort study from a national registry from January 2008 to July 2019. Sixty patients had an AH/EC and received progestin treatment using chlormadinone acetate for at least 3 months. After remission, 31 patients underwent IVF and 29 did not. The primary outcome was the recurrence rate at 24 months according to the use of IVF. The secondary outcome was the identification of risk factors for recurrence. RESULTS: The probability of 2-year recurrence was 37.7% (SD 10.41%) in the IVF group and 55.7% (SD 14.02%) in the no IVF group (P = 0.13). Obesity, nulliparity, polycystic ovary syndrome, age and tumoural characteristics were not associated with recurrence. Pregnancy was a protective factor for recurrence, with 2-year recurrence probabilities of 20.5% and 62.0% in the pregnancy and no pregnancy groups, respectively (P = 0.002, 95% CI 0.06-0.61). In contrast, the number of cycles, maximum serum oestradiol concentration during ovarian stimulation, ovarian stimulation protocol, total dose of gonadotrophin administered and thickness of the endometrium showed no significant differences in terms of the risk of recurrence in the IVF subgroup. CONCLUSION: IVF treatment after fertility-sparing management of AH/EC does not increase the risk of recurrence. Therefore, it is an acceptable strategy to decrease the time to pregnancy. Overall, the recurrence rate is high enough to justify close monitoring once remission occurs.

Long-term follow-up of endometriosis surgery in Ontario: a population-based cohort study.

BACKGROUND: Endometriosis is a chronic gynecological disease affecting approximately 10% of reproductive aged females and leads to decreased quality of life and productivity. Despite effective medical options, many women do require surgery for endometriosis. There is limited literature examining long term outcomes of endometriosis surgery. OBJECTIVE: This study aimed to characterize the long-term outcomes, including recurrence of symptoms, fertility outcomes, and need for reoperation, of patients who underwent surgical management for endometriosis. STUDY DESIGN: This was a population-based cohort study in which the universal coverage health database for the province of Ontario, Canada, was used to identify women aged 18 to 50 years who underwent surgery for endometriosis from April 1, 2002, through March 31, 2018. Surgery was classified as diagnostic laparoscopy, conservative or uterine preserving (minor or major, with and without ovarian preservation), or hysterectomy (with and without ovarian preservation). The outcomes were evaluated from 30 days after the index surgery to the end of the study period or at censoring. Cox proportional hazard regression models were used to estimate the hazard ratios between exposures and outcomes following adjustment for confounders. RESULTS: A total of 84,885 women 2,718 (3.2%) diagnostic laparoscopy, 21,594 (25.4%) minor conservative surgery, 28,484 (33.6%); major conservative with ovarian preservation, 2,102 (2.5%) major conservative without ovarian preservation, 21,609 (25.5%) hysterectomy with ovarian preservation, and 8,378 (9.9%) hysterectomy without ovarian preservation) were included in the cohort and followed for a median of 10 years (interquartile range, 6-13 years). In the first postoperative year, women who underwent diagnostic laparoscopy were significantly more likely to require repeat surgery (adjusted hazard ratio, 1.68; 95% confidence interval, 1.51-1.87), whereas those who underwent major conservative surgery were significantly less likely to require repeat surgery (with ovarian preservation: adjusted hazard ratio, 0.44; 95% confidence interval, 0.41-0.48; without ovarian preservation: adjusted hazard ratio, 0.05; 95% confidence interval, 0.03-0.09). Among women who did not receive repeat surgery in the first year, those who underwent a diagnostic laparoscopy (adjusted hazard ratio, 0.85; 95% confidence interval, 0.76-0.95) and major conservative surgery without ovarian preservation were less likely to undergo repeat surgery (adjusted hazard ratio, 0.12; 95% confidence interval, 0.09-0.18) than those who initially had minor surgery. Compared with those who initially underwent minor surgery, patients who underwent other treatment modalities were less likely to undergo a hysterectomy (diagnostic laparoscopy: adjusted hazard ratio, 0.85; 95% confidence interval, 0.75-0.96; major surgery with ovarian preservation: adjusted hazard ratio, 0.60; 95% confidence interval, 0.57-0.64; major surgery without ovarian preservation: adjusted hazard ratio, 0.05; 95% confidence interval, 0.03-0.08). Following minor and major conservative with ovarian preservation surgery, 8,331 (38.6%) and 9,498 (33.3%) of patients sought an infertility consult within 1 year, respectively. By 5 years after the index surgery, 5,290 (29.4%) of patients who had minor conservative surgery and 4,528 (20.7%) of those who had major conservative with ovarian preservation surgery had given birth at least once. CONCLUSION: Our study suggests that only a few endometriosis patients who undergo hysterectomy surgery require repeat surgery; however, up to 1 in 4 who undergo minor surgery and 1 in 5 who undergo major conservative surgery with ovarian preservation require additional endometriosis surgery. Up to 1 in 3 patients who had uterine sparing endometriosis surgery subsequently sought an infertility assessment. These findings may inform preoperative counseling in terms of recurrence of symptoms, fertility outcomes, and need for reoperation of women seeking surgical management for endometriosis. Future studies should consider the outcomes of patient satisfaction and quality of life based on the current practices for management of endometriosis.

Factors Associated with Torsion in Pediatric Patients with Ovarian Masses.

BACKGROUND: Management of ovarian torsion has evolved toward ovarian preservation regardless of ovarian appearance during surgery. However, patients with torsion and an ovarian neoplasm undergo a disproportionately high rate of oophorectomy. Our objectives were to identify factors associated with ovarian torsion among females with an ovarian mass and to determine if torsion is associated with malignancy. METHODS: A retrospective review of females aged 2-21 y who underwent an operation for an ovarian cyst or neoplasm between 2010 and 2016 at 10 children's hospitals was performed. Multivariate logistic regression was used to assess factors associated with torsion. Imaging data were assessed for sensitivity, specificity, and predictive value in identifying ovarian torsion. RESULTS: Of 814 girls with an ovarian neoplasm, 180 (22%) had torsion. In risk-adjusted analyses, patients with a younger age, mass size >5 cm, abdominal pain, and vomiting had an increased likelihood of torsion (P < 0.01 for all). Patients with a mass >5 cm had two times the odds of torsion (odds ratio: 2.1; confidence interval: 1.2, 3.6). Imaging was not reliable at identifying torsion (sensitivity 34%, positive predictive value 49%) or excluding torsion (specificity 72%, negative predictive value 87%). The rates of malignancy were lower in those with an ovarian mass and torsion than those without torsion (10% versus 17%, P = 0.01). Among the 180 girls with torsion and a mass, 48% underwent oophorectomy of which 14% (n = 12) had a malignancy. CONCLUSIONS: In females with an ovarian neoplasm, torsion is not associated with an increased risk of malignancy and ovarian preservation should be considered.

A randomized controlled trial to evaluate omentum-preserving gastrectomy for patients with T1-T3 gastric cancer.

Although complete omentectomy is traditionally performed in patients with gastric cancer as part of radical gastrectomy to ensure the elimination of micrometastases, the prognostic value of omentectomy during gastrectomy remains unclear. Retrospective studies have shown that the incidence of metastases in the greater omentum is very low in T1-T3 gastric cancer. Thus radical gastrectomy with D2 lymphadenectomy and preservation of the greater omentum may be a proper curative treatment for gastric cancer patients with T1-T3 tumors. The aim of this article is to describe the design and rationale for this prospective, randomized controlled DRAGON-05 trial, conducted to evaluate the prognostic value of omentum-preserving gastrectomy for patients with T1-T3 gastric cancer. Clinical trial registration: ChiCTR2000040045 (ClinicalTrials.gov).

Oncologic outcomes of uterine preservation for pre-menopausal patients with stage II epithelial ovarian carcinoma.

OBJECTIVE: Fertility-sparing surgery is rarely offered for patients with stage II epithelial ovarian carcinoma. The aim of the present study was to evaluate the overall survival of pre-menopausal patients with stage II epithelial ovarian carcinoma who did not undergo hysterectomy. METHODS: The National Cancer Database was accessed, and patients aged ≤40 years without a history of another tumor diagnosed between 2004 and 2015 with a pathological stage II epithelial ovarian carcinoma, who underwent lymphadenectomy and received multi-agent chemotherapy, were identified. Overall survival was compared with the log-rank test after generation of Kaplan-Meier curves. A Cox model was constructed to control for tumor histology. RESULTS: A total of 185 patients met the inclusion criteria. The rate of uterine preservation was 24.3% (45 patients). Patients who did not undergo hysterectomy were younger (median 32 vs 37 years, p<0.001) and less likely to have high-grade tumors compared with those who underwent hysterectomy. The two groups were comparable in terms of presence of co-morbidities and performance of adequate lymphadenectomy (p>0.05). Median follow-up of the present cohort was 62.3 months (95% CI 53.6 to 71.0) and a total of 22 deaths occurred. There was no difference in overall survival between patients who did and did not undergo hysterectomy (p=0.50; 5-year overall survival rates 87.5% and 91.4%, respectively). After controlling for tumor histology, grade and substage, omission of hysterectomy was not associated with worse survival (HR 0.69, 95% CI 0.22 to 2.12). CONCLUSIONS: Uterine preservation was not associated with worse survival in this cohort of pre-menopausal patients with stage II epithelial ovarian carcinoma.

Nerve-sparing in Gynecologic Surgery: A Perspective.

OBJECTIVE: To provide a perspective on nerve-sparing (NS) surgery in gynecology. DATA SOURCES: Literature review, English language. METHODS OF STUDY SELECTION: Systematic reviews and meta-analyses studies were selected for review for oncology; comparative studies were selected for endometriosis, and 1 comparative and 1 prospective study were chosen for sacrocolpopexy. TABULATION, INTEGRATION, AND RESULTS: Two tables summarize the results of systematic reviews and meta-analyses in oncology. Oncology, endometriosis, and urogynecology sections. Primary benefit of NS technique is decreased bladder dysfunction, and, to a lesser degree, vaginal and rectal dysfunc. CONCLUSION: NS is preferable to conventional surgery for benign and malignant conditions to reduce postoperative bladder, rectal, and vaginal dysfunction.

Does ovarian preservation have an effect on recurrence of early stage low-grade endometrial stromal sarcoma?

Surgical treatment of low-grade endometrial stromal sarcoma consists of hysterectomy. The role of oophorectomy is yet to be established. We aimed to examine the effect of preserving the ovaries on the pattern of recurrences in patients with stage I disease. Thirty-four patients with stage I low-grade endometrial stromal sarcoma were retrospectively analysed. Based on ovarian preservation the whole cohort was divided into two groups. Recurrence (liver, lung, groin and bone) was detected in 4 (11.8%) cases. No significant differences in overall survival or disease-free survival (DFS) were observed between the ovarian preservation and bilateral salpingo-oophorectomy (BSO) groups. Subset analysis revealed no significant difference in DFS between the ovarian preservation and BSO groups in the premenopausal arm. And also, the performance of pelvic (n = 2) or para-aortic lymphadenectomy (n = 6) or adjuvant hormonal therapy did not alter DFS significantly. The 5-year DFS rate for the group which received adjuvant radiotherapy was 62.5 and 94.4% for those which did not (p = .014). Preserving the ovaries had no adverse effect on the recurrence of stage I disease.IMPACT STATEMENTWhat is already known on this subject? Due to the rarity of the disease and the common postoperative diagnosis, only retrospective studies have been reported on low-grade endometrial stromal sarcoma. This disease is commonly diagnosed in premenopausal patients during the early stage. There is no consensus on preserving the ovaries, particularly in young patients, due to the tumour's hormonal characteristics and the risk of late recurrences.What do the results of this study add? Ovarian preservation had no effect on the recurrence of stage I low-grade endometrial stromal sarcoma. Lymphadenectomy and adjuvant hormonal treatment had no effect on DFS, and adjuvant radiotherapy decreased DFS in the current study.What are the implications of these findings for clinical practice and/or further research? Ovarian preservation should be considered, to prevent the negative effects of surgical menopause, particularly in young patients.

Trends in Renal Tumor Surgery in the United States and Germany Between 2006 and 2014: Organ Preservation Rate Is Improving.

BACKGROUND: Nephron-sparing surgery (NSS) is the treatment of choice for T1 renal tumors. This study compared the implementation of NSS in the United States and Germany. METHODS: Data were derived from the National Inpatient Sample and from the Nationwide German Hospital Billing Database. All cases of NSS and radical nephrectomy from 2006 to 2014 were analyzed. To assess tumor stage distribution, data from the Surveillance, Epidemiology, and End Results database (United States) and from German cancer registries were used. RESULTS: The study identified 74,663 cases in the United States and 130,051 cases in Germany. The proportion of NSS for T1 tumors increased from 30.6 to 57% in the United States compared with 38.5 to 72.9% (estimation) in Germany (p < 0.001). The proportion of robotic NSS increased from 0 to 54.5% in the United States (p < 0.001) and from 0.2 to 8.6% in Germany (p < 0.001). In a multivariate model, hospitals with higher annual caseloads and a surgical robot favored NSS. CONCLUSION: Patients with renal tumors might receive inhomogeneous care based on the resources of the treating institution. The robotic approach is a key driver for better implementation of NSS in the United States, and relevant potential still may exist for more organ preservation.

Staging procedures fail to benefit women with borderline ovarian tumours who want to preserve fertility: a retrospective analysis of 448 cases.

BACKGROUND: To evaluate the effect of clinicopathologic factors on the prognosis and fertility outcomes of BOT patients. METHODS: We performed a retrospective analysis of BOT patients who underwent surgical procedures in West China Second University Hospital from 2008 to 2015. The DFS outcomes, potential prognostic factors and fertility outcomes were evaluated. RESULTS: Four hundred forty-eight patients were included; 52 recurrences were observed. Ninety-two patients undergoing FSS achieved pregnancy. No significant differences in fertility outcomes were found between the staging and unstaged surgery groups. Staging surgery was not an independent prognostic factor for DFS. Laparoscopy resulted in better prognosis than laparotomy in patients with stage I tumours and a desire for fertility preservation. CONCLUSION: Patients with BOT fail to benefit from surgical staging. Laparoscopy is recommended for patients with stage I disease who desire to preserve fertility. Physicians should pay more attention to risk of recurrence in patients who want to preserve fertility.

Treatment Patterns and Distance to Treatment Facility for Soft Tissue Sarcoma of the Extremity.

BACKGROUND: The impact that distance traveled to receive treatment has on treatments and outcomes among patients with soft tissue sarcoma (STS) of the extremity has yet to be thoroughly investigated. METHODS: Information on patients treated for STS of the extremity between 2006 and 2015 was obtained from the National Cancer Database. Patients were stratified into two groups based on median distance traveled to receive treatment. Chi-square tests assessed associations between categorical variables and distance to treatment. Kaplan-Meier survival estimates and Cox regression were used to estimate survival. RESULTS: The sample included 21,763 patients. The mean age was 59.3 y, 54.6% were men, and 83.2% were white. The median distance traveled to the treating facility was 15.6 miles. Compared with patients who traveled <15 miles, those who traveled ≥15 miles were more likely to have undifferentiated rather than well-differentiated tumors (odds ratio [OR], 1.23; 95% confidence interval [95% CI], 1.10-1.37), and stage II rather than stage I disease (OR, 1.14; 95% CI, 1.04-1.24). They were also more likely to undergo limb-sparing resection (OR, 1.58; 95% CI, 1.39-1.79) or amputation (OR, 1.72; 95% CI, 1.44-2.07) rather than no surgery and less likely to have positive margins (OR, 0.86; 95% CI, 0.79-0.93). There was no difference in the risk of death between patients who traveled ≥15 miles and those who did not (hazard ratio, 1.00; 95% CI, 0.94-1.07). CONCLUSIONS: Although clinical characteristics and treatments may differ based on distance traveled, survival appears equivalent. Further research into reasons why greater distance traveled is associated with more advanced disease, but comparable survival is warranted.
