RESUMEN
BACKGROUND: Tumor recurrence, anorectal and urinary dysfunction, and lower limb dysfunction after surgery are observed in infantile sacrococcygeal teratoma (SCT). In this paper, a multi-institutional retrospective observational study was conducted to clarify the long-term functional prognosis in Japan. METHODS: This study was conducted using a paper-based questionnaire distributed to 192 facilities accredited by the Japanese Society of Pediatric Surgeons, covering patients who underwent radical surgery at less than 1 year old and who survived for at least 180 days after birth from 2000 to 2019. RESULTS: A total of 355 patients were included in this analysis. Altman type was I-II in 248 and type III-IV in 107, and the median maximum tumor diameter was 6.1 (range: 0.6-36.0) cm. There were 269 mature teratomas, 69 immature teratomas, and 10 malignant tumors. Total resection was performed in 325, subtotal or partial resection in 27, and surgical complications were noted in 54. The median postoperative follow-up was 6.6 (0.5-21.7) years. Eighty-three patients (23.4 %) had functional sequelae, including 62 (17.5 %) with anorectal dysfunction, 56 (13.0 %) with urinary dysfunction, and 15 (4.2 %) with lower limb motor dysfunction. Recurrence occurred in 42 (11.8 %) at a median age of 16.8 (1.7-145.1) months old. Risk factors for dysfunction included preterm delivery, a large tumor diameter, Altman type III-IV, incomplete resection, and surgical complications. Risk factors for recurrence included immature teratoma or malignancy, incomplete resection, and surgical complications. CONCLUSIONS: Postoperative dysfunction was not low at 23.4 %, and 11.8 % of the patients experienced recurrence occurring more than 10 years after surgery, suggesting the need for periodic imaging and tumor markers evaluations in patients with risk factors. It is necessary to establish treatment guidelines for best practice monitoring of the long-term quality of life. LEVEL OF EVIDENCE: Level II Retrospective Study.

OBJECTIVE: The aim of the study was to evaluate the prevalence of malignancy on contrast-enhanced computed tomography (CT) of the abdomen and pelvis in patients with unexplained, unintentional weight loss (UUWL). METHODS: This is a retrospective review of 999 adult outpatient contrast-enhanced CT of the abdomen and pelvis for UUWL. Patients were stratified into 2 groups: (1) weight loss only (WLO, n = 222) and (2) UUWL with additional symptoms (UUWL+, n = 777). χ2 test was performed to compare malignancy detection rate in the WLO and UUWL+ groups. RESULTS: Prevalence of malignancy was 5.3% (95% confidence interval [CI], 4.2%-7.1%; 55 of 999). Prevalence of malignancy in the WLO group was 2.3% (95% CI, 0.7%-5.2%; 5 of 222), lower than the prevalence of 6.2% (95% CI, 4.6%-8.1%; 48 of 777) in the UUWL+ group (P = 0.02). Prevalence of malignancy was lower in patients younger than 60 years in all patients and in the UUWL+ subgroup (P < 0.01 in both cases). CONCLUSIONS: There is low prevalence of malignancy on contrast-enhanced CT of the abdomen and pelvis in patients with UUWL, particularly in younger patients and those without additional symptoms.

BACKGROUND: The local recurrence of rectal cancer has been improved by total mesorectal excision following neoadjuvant chemoradiotherapy. However, in patients with low locally advanced rectal cancer, lateral pelvic recurrence remains to be addressed. OBJECTIVE: This study aimed to determine the efficiency of neoadjuvant radiotherapy in addressing lateral pelvic recurrence and which subgroup of patients might be optimal to receive lateral lymph node dissection. DESIGN: The MRI/CT images were reassessed for lateral lymph node status. The lateral lymph nodes with short axis ≥5 mm and ≥4 mm were considered positive in pretreatment and restaging MRI/CT. SETTING: This was a post hoc analysis of a prospective randomized controlled trial (FOWARC, NCT01211210). PATIENTS: A total of 495 patients with stage II or III rectal adenocarcinoma were included in the original trial. According to the excluding criteria, the finally included population consists of 253 patients; of these, 195 patients received neoadjuvant chemoradiotherapy and 94 received chemotherapy alone. MAIN OUTCOMES AND MEASURES: The primary outcome was the 5-year lateral pelvic recurrence rate. RESULTS: Compared with patients receiving chemotherapy alone, patients receiving additional radiotherapy had a marginal significance of lower lateral pelvic recurrence rate (6.6% vs 13.0%; p = 0.051). In the subset with pretreatment positive lateral lymph nodes, patients had a lateral pelvic recurrence rate of 22.6% and 45.1% after neoadjuvant chemoradiotherapy and chemotherapy alone. Of note, 34.9% of the pretreatment positive lateral lymph nodes were persistent after neoadjuvant chemoradiotherapy, culminating in a lateral pelvic recurrence rate of 63.3%. LIMITATIONS: This is a post hoc analysis, and only the patients from the leading center were included, which limited the sample size. In addition, the lateral lymph node dissection was not performed in this cohort. CONCLUSIONS: The addition of radiotherapy in neoadjuvant regimens could not address lateral pelvic recurrence adequately. Some subgroups of patients might need additional dissection.

LA INCLUSION DE LA RADIOTERAPIA PREOPERATORIA ES INSUFICIIENTE EN EL CONTROL PLVICO LATERAL EN UN SUBGRUPO DE PACIENTES CON CNCER DE RECTO INFERIOR LOCALMENTE AVANZADO UN ESTUDIO POSTHOC CONTROLADO Y RANDOMIZADO: ANTECEDENTES:La recurrencia local del cancer de recto ha disminuido al efectuar una excision mesorrectal total seguida de quimioradioterapia neoadyuvante. No obstante, en pacientes con cancer de tercio inferior de recto avanzado localmente, aún está por controlarse la recurrencia pélvicaOBJETIVOS:Determinar la eficacia de la radioterapia neoadyuvante en el control de la recurrencia pélvica lateral y en que subgrupo de pacientes sería conveniente efecutar una excisión lateral de las cadenas ganglionares.DISEÑO:Se reevaluaron las imágenes tomográficas y de resonancia magnética del status de las cadenas ganglionares linfáticas laterales. Los ganglios linfáticos laterales con un eje-corto > 5 mm y ≥ 4 mm se consideraron como positivos previo al tratamiento y reestadificados con RM y TAC respectivamente.ESCENARIO:Es un análisis post hoc de un studio prospectivo randomizado controlado (FOWARC, NCT01211210).PACIENTESSe incluyeron un total de 495 pacientes en estdio II o III con adenomcarcinoma rectal en el estudio original. De acuerdo a los criterios de exclusión, la población final incluida consistió en 253 pacientes; de estos, 195 recibieron quimioradioterapia neoadyuvante y 94 quimioterapia sola.EVALUACION DE LOS RESULTADOS PRINCIPALES:El parámetro mas importante fue la tasa de recurrencia pélvica lateral a cinco años.RESULTADOS:En comparación con los pacientes que recibieron quimioterapia sola, aquellos que además fueron sometidos a radioterapia adicional presentaron un margen significativo de menor tasa de recurrencia pélvica lateral (6.6% vs. 13.0%; p=0.051). En el grupo de pacientes con ganglios linfáticos laterales positivos, los enfermos presentaron una tasa de recurrencia pélvica lateral de 22.6% y 45.1% después de quimioradiaterapia neoadyuvante en comparación con quimioterapia sola respectivamente. Cabe mencionar que el 34.9% de los pacientes con ganglios linfáticos laterales positivos antes del tratamiento persistieron después de la quimioradioterapia neoadyuvante, reportándose finalmente una recurrencia pélvica lateral de un 63.3%.LIMITACIONES:Se trata de un análisis posthoc y solo los pacientes del hospital fueron incluidos, lo que limita el tamaño de la muestra. Además, no se efectuó la disección de los ganglios linfáticos laterales en este grupo.CONCLUSIONES:La radioterapia en los esquemas de neoadyuvancia no logran controlar la recurrencia pélvica lateral en forma adecuada. Algunos subgrupos de pacientes podría requerir de disección adicional. Consulte Video Resumen en http://links.lww.com/DCR/B613.

BACKGROUND AND AIMS: There is a lack of research on metastatic renal pelvis cell carcinoma in the current literature. In this study, we aimed to detect distant metastatic patterns in renal pelvis cell carcinoma, and illustrated the affection of different metastatic sites, surgery to primary site and chemotherapy on prognosis outcomes in patients with diverse conditions. METHODS: We collected data between 2010 and 2015 from the Surveillance, Epidemiology and End Results database. Kaplan-Meier analysis with log-rank test was used for survival comparisons. Multivariate Cox regression model was employed to analyze the effect of distant metastatic sites on overall survival (OS) and cancer-specific survival (CSS). RESULTS: A total of 424 patients were included in the analysis, the median follow-up time was 5 months (interquartile range (IQR): 2-12) and 391 deaths (92.2%) in all patients were recorded. Among them, 192 (45.3%), 153 (36.1%), 137 (32.3%) and 127 (30.0%) patients were diagnosed with lung, bone, liver and brain metastases, respectively, while only 12 (2.8%) patients had brain metastases. The bi-organ, tri-organ and tetra-organ metastatic pattern was found in 135 (31.8%), 32 (7.5%) and 11 (2.6%) patients, respectively. The multivariate Cox analyses showed that distant lymph nodes (DL) metastases was not an independent prognostic factor for both OS and CSS (OS: Hazard ratios (HR) = 1.1, 95% CI = 0.8-1.4, P = 0.622; CSS: HR = 1.0, 95% CI = 0.8-1.3, P = 0.906). Besides, there was no significant difference of survival in patients with T3-T4 stage (OS: HR = 0.8, 95% CI = 0.5-1.2, P = 0.296; CSS: HR = 0.8, 95% CI = 0.5-1.2, P = 0.224), N2-3 stage (OS: HR = 0.8, 95% CI = 0.5-1.3, P = 0.351; CSS: HR = 0.7, 95% CI = 0.4-1.2, P = 0.259) and multi-organ metastases (OS: HR = 0.8, 95% CI = 0.5-1.3, P = 0.359; CSS: HR = 0.7, 95% CI = 0.4-1.2, P = 0.179) between surgery to primary site group and no-surgery to primary site group. CONCLUSION: we described the metastatic patterns of mRPCC and the prognosis outcomes of DL metastases, surgery to primary site and chemotherapy. Our findings provide more information for clinical therapeutic intervention and translational study designs.

BACKGROUND: Despite improved surgical and oncological treatment, ovarian cancer continues to be the most lethal of the gynecologic malignancies. We aimed to analyze survival trends in epithelial ovarian cancer with regard to age, tumor site, and morphology in Sweden 1960 to 2014. METHODS: A nationwide population-based study was conducted using data from the Swedish Cancer Registry on 46,350 women aged 18 or older with a diagnosis of epithelial ovarian, fallopian tube, peritoneal, or undesignated abdominal/pelvic cancer 1960 to 2014. Analyses of age-standardized incidence and relative survival (RS) were performed and time trends modelled according to age, tumor site, and morphology. RESULTS: Overall incidence of ovarian, tubal, peritoneal, and undesignated abdominal/pelvic cancers declined since 1980. Median age at diagnosis increased. Serous carcinoma increased in incidence. RS at 1, 2 and 5 years from diagnosis improved since 1960, although not for the youngest and the oldest patients. Ten-year RS did not improve. The best RS was found for fallopian tube cancer and the worst RS for undesignated abdominal/pelvic cancer. Among the morphologic subgroups, endometrioid carcinoma had the best RS. CONCLUSIONS: Survival in epithelial ovarian, tubal, peritoneal, and undesignated abdominal/pelvic cancers in Sweden has improved over the last six decades. Advances in epithelial ovarian cancer treatment have extended life for the first 5 years from diagnosis but 10-year survival remains poor.

BACKGROUND: We aimed to characterize body composition, metabolic impairments, and physical performance among survivors of pediatric abdominal and pelvic solid tumors. METHODS: Participants included 431 survivors of abdominal or pelvic tumors [median attained age = 29.9 (range: 18.7-55.1) years]. Relative lean mass and fat mass were assessed with dual X-ray absorptiometry. Metabolic outcomes [insulin resistance (IR), high-density lipoprotein (HDL), low-density lipoprotein, and triglycerides] were based on laboratory values and medication usage. General linear regression evaluated associations between treatment and lifestyle with body composition; binomial regression evaluated associations between body composition and metabolic outcomes and physical performance. RESULTS: Lean mass was lower than values from the National Health and Nutrition Examination Survey (NHANES) in males (Z-score = -0.67 ± 1.27; P < 0.001) and females (Z-score = -0.72 ± 1.28; P < 0.001). Higher cumulative abdominal and pelvic radiation doses were associated with lower lean mass among males [abdominal: ß = -0.22 (SE) ± 0.07; P = 0.002 and pelvic: ß = -0.23 ± 0.07; P = 0.002] and females (abdominal: ß = -0.30 ± 0.09; P = 0.001 and pelvic: ß = -0.16 ± 0.08; P = 0.037). Prevalence of IR (40.6% vs. 33.8%; P = 0.006), low HDL (28.9% vs. 33.5%; P = 0.046), and high triglycerides (18.4% vs. 10.0%; P < 0.001) was increased among survivors relative to NHANES. Compared with survivors with normal/high lean mass and normal/low fat mass, survivors with normal/high lean mass and high fat mass had an increased risk of IR (P < 0.001), low HDL (P < 0.001), reduced quadriceps strength at 60°/second (P < 0.001) and 300°/second (P < 0.001), and reduced distance covered in the 6-minute walk (P < 0.01). CONCLUSIONS: Abdominal/pelvic radiotherapy is associated with body composition changes that can adversely influence metabolic outcomes and performance status among survivors. IMPACT: Interventions targeting body composition may facilitate management of cardiovascular disease risk in this population.

OBJECTIVES: The purpose of this report is to describe the effect of computed tomography-guided bilateral pudendal nerve cryoablations on pain and time to discharge in the setting of acute hospitalizations secondary to refractory pelvic pain from cancer. METHODS: Investigators queried the medical record for patients who underwent pudendal nerve cryoablation using the Category III Current Procedural Technology code assignment 0442T or Category I code 64640 for cases prior to 2015. The resulting list was reviewed, and procedures performed on inpatients for intractable pelvic pain related to neoplasm were selected. The final cohort was then analyzed with regard to patient demographics, procedure details, technical success, safety, pain scores, and time to discharge. RESULTS: Ten patients underwent cryoablation by 3 operators for palliation of painful pelvic neoplasms between June 2014 and January 2019. All probes were satisfactorily positioned and freeze cycles undertaken without difficulty. There were no procedure-related complications or adverse events. The mean difference in pre- and posttreatment worst pain scores was significant (n = 5.20, P = .003). The mean time to discharge following the procedure was 2.3 days. CONCLUSION: Computed tomography-guided percutaneous cryoablation of the bilateral pudendal nerves may represent a viable option in the setting of acute hospitalization secondary to intractable pain in patients with pelvic neoplasms.

Pelvic mass onset following a hysterectomy due to benign disease is not rarely seen. Appropriate diagnosis and treatment are of great importance.This study aims to analyze the clinicopathological features of patients who have received surgery for pelvic mass following hysterectomy due to gynecological benign disease, especially endometriosis or adenomyosis.This study retrospectively analyzed the patients undergone reoperation for pelvic mass subsequently to hysterectomy from January 2012 to December 2016 in a tertiary teaching hospital.A total of 247 patients were enrolled in this study. There is a significant difference between the patients with or without a history of endometriosis/adenomyosis. Multivariate analysis showed that the pelvic mass had a higher risk of being ovarian endometrioid carcinoma, ovarian clear cell carcinoma, ovarian endometriosis, and ovarian physiological cysts in patients with a history of adenomyosis/endometriosis.The pathology of the subsequent pelvic mass inclines to be benign, includes ovarian endometriosis, ovarian physiological cysts, and pelvic encapsulated effusion. Postoperative adjuvant therapy for those received hysterectomy due to endometriosis/adenomyosis, like gonadotropin releasing hormone agonists (GnRHa), may contribute to the prevention of benign pelvic mass. Patients with a history of hysterectomy due to endometrisos/adenomyosis tend to have a shorter time interval between hysterectomy and pelvic malignant tumors onset.

The incidence of abdominal and pelvic cancer in pregnancy is low, but it is rising as the population of pregnant women gets older. Depending on disease stage, gestational age and patient's preference, active surveillance as well as surgery and chemotherapy are feasible options during pregnancy. Correct diagnosis and staging of the tumor is crucial for choosing the best therapeutic approach. Moreover, a reproducible modality to assess the treatment response is requested. Magnetic resonance imaging (MRI) is commonly used with good results for the local staging and treatment response evaluation of most abdominal and pelvic cancers in nonpregnant patients, and it is considered relatively safe during pregnancy. The purpose of this article is to analyze the most relevant topics regarding the use of MRI in pregnant women with abdominal and pelvic cancer. We discuss MRI safety during pregnancy, including the use of gadolinium-based contrast agents (GBCAs), how to prepare the patient for the exam and MRI technique. This will be followed by a brief review on the most common malignancies diagnosed during pregnancy and their MRI appearance.

To analyze the clinicopathological characteristics of pelvic masses after hysterectomy for benign diseases, and to analyze the related factors of benign and malignant pelvic masses.This study retrospectively analyzed the patients undergone reoperation for pelvic mass subsequently to hysterectomy for benign disease from January 2012 to December 2016 in Peking Union Medical College Hospital.A total of 247 patients were enrolled in this study, of which 34.01% were diagnosed with malignant tumors, and 65.99% benign tumors. Comparing the clinicopathological data of patients with benign and malignant pelvic masses, significant differences were found between the 2 groups with regard to their ages of having hysterectomy and pelvic mass resection, and the time intervals between the onset of pelvic mass and hysterectomy. In addition, patients with malignant masses tended to complain of abdominal distension and abdominal pain, while most of those with benign masses were diagnosed during physical examination. Patients with malignant pelvic masses had medical imagines of mixed masses, extraovarian derivation, as well as elevated carbohydrate antigen-125 (CA 125). Multivariate analysis showed that ages of having hysterectomy, physical examination results, abnormal defecation, cystic and solid masses, and elevated CA 125 level were independent risk factors for benign and malignant pelvic masses.For patients having pelvic masses following hysterectomy for benign diseases, if they had hysterectomy later in their lives, and their masses were not found during physical examination, and had abnormal defecation, mixed cystic solid mass as well as elevated serum CA 125, it is suggested that special attention should be paid to the possibility of malignant tumors.

Surgery for retroperitoneal sarcomas should be "en bloc" compartmental, which involves resection of unaffected organs. Its upfront use is key, providing a high percentage of resections with negative margins, resulting in a better local control and increased survival in many patients. Preservation of organs should be done in an individualized manner, especially in the pelvic location, and adapted to the histological aggressiveness of the tumor. Preoperative biopsy is able to establish the diagnosis of sarcoma subtype and consequently an adequate perioperative strategy. These patients should be managed by expert surgeons at referral centers with multidisciplinary units and oncology committees. The use of chemotherapy and radiotherapy is not yet well defined, so it is only recommended at referral centers with clinical trials. Currently, this is the only option to offer the best morbidity and mortality rates, as well as possible improvements in the survival of these patients.

OBJECTIVES: The aim of the study was to describe the experience of one institution in management and outcome of tubo-ovarian abscess (TOA) in pre- and postmenopausal women and to reassess the optimal approach for TOA in postmenopausal women. METHODS: A retrospective cohort study included women diagnosed with TOA between 2003 and 2017 in a tertiary referral center. TOA was diagnosed by sonography or computerized tomography and at least one of the following criteria: temperature more than 38°C, leukocytosis more than 15,000 mm, or surgically proven disease. Women were followed up for a mean of 7.6 years (range 6 mo to 14 y). The rates of conservative management and pelvic malignancy were evaluated. RESULTS: The study cohort included 144 (69.23%) women who met the inclusion criteria, of which 105 (72.92%) were premenopausal and 39 (27.08%) were postmenopausal. Univariate analysis found no differences in risk factors and disease characteristics between the two groups. Among the study sample, 22 (56.4%) postmenopausal women and 48 (45.7%) premenopausal women were treated surgically (Pâ=â0.5). None of the premenopausal women and 1 (2.6%) postmenopausal woman were diagnosed with pelvic malignancy. CONCLUSION: In postmenopausal women with TOA, the prevalence of concurrent pelvic malignancy was 2.6%, which is higher than in the general population, but lower than that reported in the literature; 44% were conservatively managed without any apparent cases of misdiagnoses of cancer.

BACKGROUND: One of the late complications associated with radiation therapy (RT) is a possible increased risk of second cancer. In this systematic review, we analysed the incidence of rectal cancer following primary pelvic cancer irradiation. METHODS: A literature search was conducted using the PubMed and EMBASE libraries. Original articles that reported on secondary rectal cancer after previous RT for a primary pelvic cancer were included. Sensitivity analyses were performed by correcting for low number of events, high risk of bias, and outlying results. RESULTS: A total of 5171 citations were identified during the literature search, 23 studies were included in the meta-analyses after screening. A pooled analysis, irrespective of primary tumour location, showed an increased risk for rectal cancer following RT (Nâ¯=â¯403.243) compared with non-irradiated patients (Nâ¯=â¯615.530) with a relative risk (RR) of 1.43 (95% confidence interval [CI] 1.18-1.72). Organ specific meta-analysis showed an increased risk for rectal cancer after RT for prostate (RR 1.36, 95%CI 1.10-1.67) and cervical cancer (RR 1.61, 95% CI 1.10-2.35). No relation was seen in ovarian cancer patients. The modality of RT did not influence the incidence of rectal cancer. CONCLUSIONS: This review demonstrates an increased risk for second primary rectal cancer in patients who received RT to the pelvic region. This increased risk was modest and could not be confirmed for all primary pelvic cancer sites. The present study does not provide data to change guidelines for surveillance for rectal cancer in previously irradiated patients.

Mexico has seen an increase in cancer prevalence in its entire population as well as particular age ranges, predominantly the older segment. The most frequently reported pelvic cancers in Mexico are cervical, endometrial, bladder, prostate, rectum, and anal canal. Approximately 80% of the population diagnosed with pelvic cancers present with locally advanced tumors and require concomitant chemoradiotherapy, sequential chemoradiotherapy, or radiotherapy alone. The toxicity of any of these treatment modalities may be manifested as intestinal injury, a significant problem that can compromise the response to treatment, the patient's nutritional state, quality of life, and survival. In this article, we will approach key aspects in nutrition as well as the epidemiological characteristics and toxicities in patients affected by these pelvic tumors.

BACKGROUND: Pelvic exenteration carries significant risks of morbidity and mortality. Preoperative management is therefore crucial, and the exenteration procedure is usually performed in an elective setting. In cases of rectal cancer, however, tumor-related complications may cause a patient's condition to deteriorate rapidly, despite optimal management. Urgent pelvic exenteration then may be an option for these patients. OBJECTIVE: This study aims to compare the outcomes of pelvic exenteration between the urgent and elective settings. DESIGN: This is a retrospective study. SETTING: This study was conducted at King Chulalongkorn Memorial Hospital between February 2006 and June 2012. PATIENTS: Fifty-three patients with locally advanced rectal cancer were included. INTERVENTION: All patients underwent pelvic exenteration for locally advanced rectal cancer. They were assigned to urgent and elective setting groups according to their preoperative conditions. The urgent setting group included patients who required urgent pelvic exenteration because of intestinal obstruction, bowel perforation, bleeding, or uncontrolled sepsis, despite optimal management preoperatively. MAIN OUTCOME MEASURES: Twenty-six patients were classified in the urgent setting group, and 27 were classified in the elective setting group. Three-year overall and disease-free survivals were compared between the 2 groups. Thirty-day postoperative morbidity and mortality were also studied. RESULTS: Three-year overall survival was 62.2% and 54.4% in the elective and urgent groups (p = 0.7), whereas three-year disease-free survival was 43% and 63.8% (p = 0.33). The median follow-up time was 33 months. Thirty-day morbidity did not differ between the 2 groups (p = 0.49). A low serum albumin level was a significant risk factor for complications. There was no postoperative mortality in this study. LIMITATIONS: This was a retrospective study performed at 1 institution, and it lacked quality-of-life scores. CONCLUSION: Pelvic exenteration in an urgent setting is feasible and could offer acceptable outcomes. See Video Abstract at http://links.lww.com/DCR/A591.

OBJECTIVE: To assess whether there is any association between the implantation of synthetic polypropylene mesh slings for the treatment of stress urinary incontinence (SUI) and risk of cancer. METHODS: We performed a nationwide cohort study based on the general female population in Sweden. All women entered the observational period as unexposed on January 1, 1997, and contributed person-time as unexposed unless they underwent a midurethral sling procedure for SUI, after which they contributed person-time as exposed until first occurrence of any cancer, death, emigration, or end of the observational period (December 31, 2009). Occurrence of primary cancer was ascertained from the Cancer Register. Hazard ratios (HRs) with 95% CIs were calculated by Cox proportional hazards regression. RESULTS: The final study population included 5,385,186 women, including 20,905 exposed, encompassing a total of 44,012,936 person-years at risk. Other than an inverse association with rectal cancer (HR 0.5, 95% CI 0.3-0.8), there were no significant differences in risk between exposed and unexposed women for pelvic organ cancers including ovarian (HR 0.8, 95% CI 0.5-1.2), endometrial (HR 1.1, 95% CI 0.8-1.4), cervical (HR 0.4, 95% CI 0.2-1.0), bladder, and urethra (HR 0.7, 95% CI 0.4-1.2). No significant association was observed between exposed women and primary cancer in any organ system when compared with unexposed women. The relative risk for cancer after exposure showed little variation over time except for an inverse overall correlation within the first 4 years of surgery (HR 0.7, 95% CI 0.7-0.8). The incidence rates per 100,000 person-years (95% CIs) for exposed vs unexposed women were 20.5 (14.3-29.5) vs 21.0 (20.6-21.5) for rectal cancer, 25.5 (18.4-35.3) vs 19.8 (19.4-20.2) for ovarian cancer, 65.0 (53.0-79.8) vs 33.1 (32.6-33.7) for endometrial cancer, 5.7 (2.8-11.3) vs 11.9 (11.6-12.2) for cervical cancer, and 19.1 (13.1-27.8) vs 13.3 (13.0-13.7) for bladder and urethra cancer. CONCLUSION: Our results suggest that midurethral polypropylene sling surgery for SUI is not associated with an increased cancer risk later in life.

OBJECTIVES: Although chemoradiation is the standard of care for anal cancer, limited data exist regarding pelvic reirradiation (re-RT) for recurrent disease. We investigated toxicity and outcomes in patients who received prior pelvic radiation therapy (RT), and subsequently underwent hyperfractionated accelerated re-RT to the pelvis for recurrent anal cancer. MATERIALS AND METHODS: We reviewed records of 10 patients with recurrent anal squamous cell carcinoma who previously received pelvic RT to at least 30 Gy as a component of their chemoradiation and underwent re-RT in 1.5 Gy twice daily fractions to the pelvis, with either preoperative (N=7) or definitive (N=3) intent. RESULTS: The 3-year disease-free survival and 3-year overall survival rates were 40% and 60%. Four patients recurred within the reirradiated field, with a 3-year freedom from local progression rate of 56%. Of the 7 patients treated with preoperative intent, 5 proceeded to surgery, of whom 3 are alive and disease-free at a median duration of 43 months. Of the 3 patients treated definitively with no surgery, all are alive and disease-free at a median duration of 84 months. Re-RT resulted in one grade 3 acute toxicity and no grade 3 or higher late complications. CONCLUSIONS: Hyperfractionated accelerated re-RT was well-tolerated in patients with previously irradiated anal cancer. Patients treated with either definitive re-RT or re-RT followed by surgical resection had excellent rates of overall survival and freedom from local progression.

PURPOSE: The incidence of localized prostate cancer has decreased with shifts in prostate cancer screening. While recent population based studies demonstrated a stable incidence of locoregional prostate cancer, they categorized organ confined, extraprostatic and lymph node positive disease together. However, to our knowledge the contemporary incidence of prostate cancer with pelvic lymph node metastases remains unknown. MATERIALS AND METHODS: We used SEER (Surveillance, Epidemiology and End Results) data from 2004 to 2014 to identify men diagnosed with prostate cancer. We analyzed trends in the age standardized prostate cancer incidence by stage. The impact of disease extent on mortality was assessed by adjusted Cox proportional hazard analysis. RESULTS: During the study period the annual incidence of nonmetastatic prostate cancer decreased from 5,119.1 to 2,931.9 per million men (IR 0.57, 95% CI 0.56-0.58, p <0.01) while the incidence of pelvic lymph node metastases increased from 54.1 to 79.5 per million men (IR 1.47, 95% CI 1.33-1.62, p <0.01). The incidence of distant metastases in men 75 years old or older reached a nadir in 2011 compared to 2004 (IR 0.81, 95% CI 0.74-0.90, p <0.01) and it increased in 2012 compared to 2011 (IR 1.13, 95% CI 1.02-1.24, p <0.05). The risk of cancer specific mortality significantly increased in men diagnosed with pelvic lymph node metastases (HR 4.5, 95% CI 4.2-4.9, p <0.01) and distant metastases (HR 21.9, 95% CI 21.2-22.7, p <0.01) compared to men with nonmetastatic disease. CONCLUSIONS: The incidence of pelvic lymph node metastases is increasing coincident with a decline in the detection of localized disease. Whether this portends an increase in the burden of advanced disease or simply reflects decreased lead time remains unclear. However, this should be monitored closely as the increase in N1 disease reflects an increase in incurable prostate cancer at diagnosis.
