RESUMO

ABSTRACT: Diffuse pigmented villonodular synovitis (PVNS) of knee is a rare benign disease that has a destructive clinical course. Synovectomy and adjuvant radiotherapy (RT) have been reported as treatment options but literatures reporting functional outcomes were sparse. This study aimed to evaluate the long-term functional outcomes and disease control among treatment modalities through the 22 years of experience.A single-center database was searched for patients who received synovectomy of knee with the pathologic diagnosis of PVNS. General data, treatment modalities, and recurrent status were retrospectively collected from medical records. Functional outcomes were evaluated by Western Ontario and McMaster Universities Osteoarthritis Index through phone interviews by an independent orthopedist.From January 1995 to December 2017, 24 patients with diffuse PVNS of knee were identified, including 19 receiving open synovectomy (OP) and 5 undergoing arthroscopic surgery. Adjuvant RT was performed on 14 patients with a median dose of 35 Gy (range 20-40 Gy). After median follow up of 6 years, recurrences were recorded in 10 cases. The recurrence rate was significantly lower in the OP + RT group than the OP group (8.3% vs 57.1%, P = .038). Among those with preserved knee joints, there was no significant difference in the Western Ontario and McMaster Universities Osteoarthritis Index score and stiffness score between patients in the OP + RT and OP groups.For patients with diffuse PVNS of knee, the addition of moderate-dose adjuvant RT following OP provided excellent local control while maintaining good joint function with limited treatment-related morbidity. Our study emphasized the importance of moderate dose RT in diffuse PVNS of knee joint.

RESUMO

BACKGROUND/AIM: Surgical resection for soft tissue sarcomas (STSs) is the gold standard for a curative oncologic therapy in combination with neoadjuvant or adjuvant radiation therapy (NRT/ART). The aim of this study was to determine prognostic factors influencing the survival of patients with STS undergoing NRT or ART considering various parameters in a retrospective, single-centre analysis over 15 years. PATIENTS AND METHODS: We included 119 patients (male 59) and the median follow-up period was 69 months (4-197). The patients received NRT (n=64) or ART (n=55). We recorded the histopathologic subtype of STS, tumour grade, localization, tumour margins, complications, survival, local recurrence, and metastases. Survival analysis was performed using the Kaplan-Meier method. RESULTS: The overall survival rate was 68.9% at 5 years. The localization (epifascial/subfascial), resection margin and type of radiation therapy (NRT/ART) had no significant impact on survival. Tumour grade, tumour size, local recurrence and metastases were significantly correlated with patient survival (p<0.05). Local recurrence was significantly higher in patients with ART (p=0.044). CONCLUSION: Tumour grade and tumour size were independently associated with disease-specific survival, and patients with local recurrence and metastases had lower survival rates.

RESUMO

PURPOSE: The summary presented herein represents Part II of the two-part series dedicated to Advanced Prostate Cancer: AUA/ASTRO/SUO Guideline discussing prognostic and treatment recommendations for patients with castration-resistant disease. Please refer to Part I for discussion of the management of patients with biochemical recurrence without metastatic disease after exhaustion of local treatment options as well as those with metastatic hormone-sensitive prostate cancer. RESULTS: The Advanced Prostate Cancer Panel created evidence- and consensus-based guideline statements to aid clinicians in the management of patients with advanced prostate cancer. Such statements are summarized in figure 1[Figure: see text] and detailed herein. MATERIALS AND METHODS: The systematic review utilized to inform this guideline was conducted by an independent methodological consultant. A research librarian conducted searches in Ovid MEDLINE (1998 to January Week 5 2019), Cochrane Central Register of Controlled Trials (through December 2018), and Cochrane Database of Systematic Reviews (2005 through February 6, 2019). An updated search was conducted prior to publication through January 20, 2020. The methodology team supplemented searches of electronic databases with the studies included in the prior AUA review and by reviewing reference lists of relevant articles. CONCLUSIONS: This guideline attempts to improve a clinician's ability to treat patients diagnosed with advanced prostate cancer. Continued research and publication of high-quality evidence from future trials will be essential to improve the level of care for these patients.

RESUMO

PURPOSE: Breast cancer patients receiving radiotherapy (RT) commonly report pain, contributing to physical and emotional distress, and potentially resulting in poor quality of life. This study prospectively identified trends and risk factors in patient-reported pain associated with breast irradiation using the Edmonton Symptom Assessment Scale (ESAS) and a study-specific Skin Symptom Assessment (SSA). METHODS: Before RT and once per week during RT, patients completed the ESAS and SSA. Upon RT completion, patients were contacted via telephone to complete both assessments weekly for 6 weeks, and a final assessment was conducted 1-3 months post-RT. Only data from patients who had completed both assessments before, at least once during, and at least once after RT were included in our analysis. RESULTS: A total of 426 patients provided data for the analysis. Overall acute pain increased significantly at week 1-2 (p < 0.0001), week 5 (p = 0.0011), and at 1-3 months (p < 0.0001) post-RT compared with baseline, and acute breast pain increased significantly at week 1 (p < 0.001) and week 2 (p = 0.0002) post-RT compared with baseline. Previous chemotherapy (adjuvant or neoadjuvant) in mastectomy patients was associated with increased overall pain compared with mastectomy patients without previous chemotherapy (p = 0.017). Younger patients (40-49 or 50-59 years of age) reported more overall pain (p = 0.0001, p = 0.038) and breast pain (p = 0.0003, p = 0.0038) compared with patients ≥ 60 years of age. CONCLUSIONS: Patient-reported pain associated with breast irradiation peaked 1 week after RT completion. Our findings provide support for closer monitoring of acute pain associated with breast RT in younger patients.

RESUMO

BACKGROUND: Adjuvant radiotherapy has been shown to halve the risk of biochemical progression for patients with high-risk disease after radical prostatectomy. Early salvage radiotherapy could result in similar biochemical control with lower treatment toxicity. We aimed to compare biochemical progression between patients given adjuvant radiotherapy and those given salvage radiotherapy. METHODS: We did a phase 3, randomised, controlled, non-inferiority trial across 32 oncology centres in Australia and New Zealand. Eligible patients were aged at least 18 years and had undergone a radical prostatectomy for adenocarcinoma of the prostate with pathological staging showing high-risk features defined as positive surgical margins, extraprostatic extension, or seminal vesicle invasion; had an Eastern Cooperative Oncology Group performance status of 0-1, and had a postoperative prostate-specific antigen (PSA) concentration of 0·10 ng/mL or less. Patients were randomly assigned (1:1) using a minimisation technique via an internet-based, independently generated allocation to either adjuvant radiotherapy within 6 months of radical prostatectomy or early salvage radiotherapy triggered by a PSA of 0·20 ng/mL or more. Allocation sequence was concealed from investigators and patients, but treatment assignment for individual randomisations was not masked. Patients were stratified by radiotherapy centre, preoperative PSA, Gleason score, surgical margin status, and seminal vesicle invasion status. Radiotherapy in both groups was 64 Gy in 32 fractions to the prostate bed without androgen deprivation therapy with real-time review of plan quality on all cases before treatment. The primary endpoint was freedom from biochemical progression. Salvage radiotherapy would be deemed non-inferior to adjuvant radiotherapy if freedom from biochemical progression at 5 years was within 10% of that for adjuvant radiotherapy with a hazard ratio (HR) for salvage radiotherapy versus adjuvant radiotherapy of 1·48. The primary analysis was done on an intention-to-treat basis. This study is registered with ClinicalTrials.gov, NCT00860652. FINDINGS: Between March 27, 2009, and Dec 31, 2015, 333 patients were randomly assigned (166 to adjuvant radiotherapy; 167 to salvage radiotherapy). Median follow-up was 6·1 years (IQR 4·3-7·5). An independent data monitoring committee recommended premature closure of enrolment because of unexpectedly low event rates. 84 (50%) patients in the salvage radiotherapy group had radiotherapy triggered by a PSA of 0·20 ng/mL or more. 5-year freedom from biochemical progression was 86% (95% CI 81-92) in the adjuvant radiotherapy group versus 87% (82-93) in the salvage radiotherapy group (stratified HR 1·12, 95% CI 0·65-1·90; pnon-inferiority=0·15). The grade 2 or worse genitourinary toxicity rate was lower in the salvage radiotherapy group (90 [54%] of 167) than in the adjuvant radiotherapy group (116 [70%] of 166). The grade 2 or worse gastrointestinal toxicity rate was similar between the salvage radiotherapy group (16 [10%]) and the adjuvant radiotherapy group (24 [14%]). INTERPRETATION: Salvage radiotherapy did not meet trial specified criteria for non-inferiority. However, these data support the use of salvage radiotherapy as it results in similar biochemical control to adjuvant radiotherapy, spares around half of men from pelvic radiation, and is associated with significantly lower genitourinary toxicity.

RESUMO

BACKGROUND: Adjuvant radiotherapy reduces the risk of biochemical progression in prostate cancer patients after radical prostatectomy. We aimed to compare adjuvant versus early salvage radiotherapy after radical prostatectomy, combined with short-term hormonal therapy, in terms of oncological outcomes and tolerance. METHODS: GETUG-AFU 17 was a randomised, open-label, multicentre, phase 3 trial done at 46 French hospitals. Men aged at least 18 years who had an Eastern Cooperative Oncology Group performance status of 1 or less, localised adenocarcinoma of the prostate treated with radical prostatectomy, who had pathologically-staged pT3a, pT3b, or pT4a (with bladder neck invasion), pNx (without pelvic lymph nodes dissection), or pN0 (with negative lymph nodes dissection) disease, and who had positive surgical margins were eligible for inclusion in the study. Eligible patients were randomly assigned (1:1) to either immediate adjuvant radiotherapy or delayed salvage radiotherapy at the time of biochemical relapse. Random assignment, by minimisation, was done using web-based software and stratified by Gleason score, pT stage, and centre. All patients received 6 months of triptorelin (intramuscular injection every 3 months). The primary endpoint was event-free survival. Efficacy and safety analyses were done on the intention-to-treat population. The trial is registered with ClinicalTrials.gov, NCT00667069. FINDINGS: Between March 7, 2008, and June 23, 2016, 424 patients were enrolled. We planned to enrol 718 patients, with 359 in each study group. However, on May 20, 2016, the independent data monitoring committee recommended early termination of enrolment because of unexpectedly low event rates. At database lock on Dec 19, 2019, the overall median follow-up time from random assignment was 75 months (IQR 50-100), 74 months (47-100) in the adjuvant radiotherapy group and 78 months (52-101) in the salvage radiotherapy group. In the salvage radiotherapy group, 115 (54%) of 212 patients initiated study treatment after biochemical relapse. 205 (97%) of 212 patients started treatment in the adjuvant group. 5-year event-free survival was 92% (95% CI 86-95) in the adjuvant radiotherapy group and 90% (85-94) in the salvage radiotherapy group (HR 0·81, 95% CI 0·48-1·36; log-rank p=0·42). Acute grade 3 or worse toxic effects occurred in six (3%) of 212 patients in the adjuvant radiotherapy group and in four (2%) of 212 patients in the salvage radiotherapy group. Late grade 2 or worse genitourinary toxicities were reported in 125 (59%) of 212 patients in the adjuvant radiotherapy group and 46 (22%) of 212 patients in the salvage radiotherapy group. Late genitourinary adverse events of grade 2 or worse were reported in 58 (27%) of 212 patients in the adjuvant radiotherapy group versus 14 (7%) of 212 patients in the salvage radiotherapy group (p<0·0001). Late erectile dysfunction was grade 2 or worse in 60 (28%) of 212 in the adjuvant radiotherapy group and 17 (8%) of 212 in the salvage radiotherapy group (p<0·0001). INTERPRETATION: Although our analysis lacked statistical power, we found no benefit for event-free survival in patients assigned to adjuvant radiotherapy compared with patients assigned to salvage radiotherapy. Adjuvant radiotherapy increased the risk of genitourinary toxicity and erectile dysfunction. A policy of early salvage radiotherapy could spare men from overtreatment with radiotherapy and the associated adverse events. FUNDING: French Health Ministry and Ipsen.

RESUMO

BACKGROUND/AIM: Palbociclib is an FDA-approved cyclin-dependent kinase inhibitor for the treatment of advanced breast cancer. Limited information is available regarding the toxicity of palbociclib and concurrent radiation therapy. CASE REPORT: Herein, we report a case of esophageal toxicity in a patient treated with palbociclib and radiation therapy. A 63-year-old woman was treated with palbociclib followed by palliative radiation therapy. The patient presented three days after completing radiation therapy with severe odynophagia, and dysphagia and was found to have grade 2-3 esophageal ulcers. Palbociclib and radiation therapy was held on admission, and a resolution of her symptoms and improvement in her oral intake was noted at which time she was restarted on palbociclib with no further radiation treatment. CONCLUSION: Caution is advised when patients are undergoing concurrent palbociclib and even low-dose palliative radiation treatment. In these patients, providers should maintain a high index of suspicion for toxicities such as dermatitis or mucositis.

RESUMO

BACKGROUND: Unlike for extremity sarcomas, the efficacy of radiotherapy for retroperitoneal sarcoma is not established. The aim of this study was to evaluate the impact of preoperative radiotherapy plus surgery versus surgery alone on abdominal recurrence-free survival. METHODS: EORTC-62092 is an open-label, randomised, phase 3 study done in 31 research institutions, hospitals, and cancer centres in 13 countries in Europe and North America. Adults (aged ≥18 years) with histologically documented, localised, primary retroperitoneal sarcoma that was operable and suitable for radiotherapy, who had not been previously treated and had a WHO performance status and American Society of Anesthesiologists score of 2 or lower, were centrally randomly assigned (1:1), using an interactive web response system and a minimisation algorithm, to receive either surgery alone or preoperative radiotherapy followed by surgery. Randomisation was stratified by hospital and performance status. Radiotherapy was delivered as 50·4 Gy (in 28 daily fractions of 1·8 Gy) in either 3D conformal radiotherapy or intensity modulated radiotherapy, and the objective of surgery was a macroscopically complete resection of the tumour mass with en-bloc organ resection as necessary. The primary endpoint was abdominal recurrence-free survival, as assessed by the investigator, and was analysed in the intention-to-treat population. Safety was analysed in all patients who started their allocated treatment. This trial is registered with ClinicalTrials.gov, NCT01344018. FINDINGS: Between Jan 18, 2012 and April 10, 2017, 266 patients were enrolled, of whom 133 were randomly assigned to each group. The median follow-up was 43·1 months (IQR 28·8-59·2). 128 (96%) patients from the surgery alone group had surgery, and 119 (89%) patients in the radiotherapy and surgery group had both radiotherapy and surgery. Median abdominal recurrence-free survival was 4·5 years (95% CI 3·9 to not estimable) in the radiotherapy plus surgery group and 5·0 years (3·4 to not estimable) in the surgery only group (hazard ratio 1·01, 95% CI 0·71-1·44; log rank p=0·95). The most common grade 3-4 adverse events were lymphopenia (98 [77%] of 127 patients in the radiotherapy plus surgery group vs one [1%] of 128 patients in the surgery alone group), anaemia (15 [12%] vs ten [8%]), and hypoalbuminaemia (15 [12%] vs five [4%]). Serious adverse events were reported in 30 (24%) of 127 patients in the radiotherapy plus surgery group, and in 13 (10%) of 128 patients in the surgery alone group. One (1%) of 127 patients in the radiotherapy plus surgery group died due to treatment-related serious adverse events (gastropleural fistula), and no patients in the surgery alone group died due to treatment-related serious adverse events. INTERPRETATION: Preoperative radiotherapy should not be considered as standard of care treatment for retroperitoneal sarcoma.

RESUMO

Immediate breast reconstruction versus delayed breast reconstruction improves quality of life of breast cancer patients undergoing total mastectomy without impacting oncologic outcomes. Two types of immediate reconstruction are possible, implant-based reconstruction or autologous reconstruction. These reconstructions interpose a tissue in the operating bed, which modifies target volume definition compared to a wall without reconstruction Post mastectomy radiotherapy increases the rate of postoperative complications for both surgical procedures. Recent guidelines were published about target volume definition in the post mastectomy setting after implant-based reconstruction. Guidelines about target volume definition after autologous reconstruction are still awaited. The aim of our work is to present the different surgical procedures for immediate breast reconstruction, their complications, and the definition of the postmastectomy target volume.

RESUMO

OBJECTIVE: Surgery followed by postoperative radiation therapy (RT) is the standard of care for soft tissue sarcomas (STS) of the head and neck that are high grade or have close or positive margins. METHODS: The authors retrospectively reviewed adult patients with head and neck STS treated with RT at a single institution between 1981 and 2017. All patients who were 19 years and older with STS of the head and neck-excluding rhabdomyosarcoma, angiosarcoma, and Ewing tumors-were included in this study. Toxicity was graded using Common Terminology Criteria for Adverse Events (CTCAE), version 4. RESULTS: Among 34 patients with head and neck STS treated with postoperative RT (33) or primary RT (1) who met the inclusion criteria, the median age at diagnosis was 45 years (range, 20 to 83). Overall, 37% had T1 tumors, 50% had high-grade histology (grade 3), and 26% had microscopically positive margins. The median RT dose was 65 Gy to the primary site; 29% received elective nodal irradiation. The median follow-up for living patients was 16.6 years (range, 0.6 to 30). At 5 and 10 years, the local control rates were 88% and 80%, the regional control rates were 97% and 97%, the freedom from distant metastases rates were 100% and 100%, the cause-specific survival rates were 88% and 81%, and the overall survival rates were 85% and 69%. Two patients (6%) developed late grade 3+ complications. CONCLUSION: Our study demonstrates that surgery and radiotherapy for STS of the head and neck have excellent disease outcomes.

RESUMO

BACKGROUND: Obesity is a risk factor for the development of secondary lymphedema after axillary lymphadenectomy and radiation therapy. The purpose of this study was to determine whether obesity influences the morbidity of lymphedema in patients who have the condition. METHODS: Two cohorts of patients were compared: group 1, normal weight (body mass index ≤25 kg/m); and group 2, obese (body mass index ≥30 kg/m). Inclusion criteria were patients aged 21 years or older with lymphedema confirmed by lymphoscintigraphy. Covariates included age, sex, lymphedema type (primary or secondary), location, comorbidities, lymph node dissection, radiation therapy, lymphoscintigram result, and disease duration. Outcome variables were infection, hospitalization, and degree of limb overgrowth. The cohorts were compared using the Mann-Whitney U test, Fisher's exact test, and multivariable logistic regression. RESULTS: Sixty-seven patients were included: group 1, n = 33; and group 2, n = 34. Disease duration did not differ between groups (p = 0.72). Group 2 was more likely to have an infection (59 percent), hospitalization (47 percent), and moderate or severe overgrowth (79 percent), compared to group 1 (18, 6, and 40 percent, respectively; p < 0.001). Multivariable logistic regression showed that obesity was an independent risk factor for infection (OR, 7.9; 95 percent CI, 2.5 to 26.3; p < 0.001), hospitalization (OR, 30.0; 95 percent CI, 3.6 to 150.8; p < 0.001), and moderate to severe limb overgrowth (OR, 6.7; 95 percent CI, 2.1 to 23.0; p = 0.003). CONCLUSIONS: Obesity negatively affects patients with established lymphedema. Obese individuals are more likely to have infections, hospitalizations, and larger extremities compared to subjects with a normal body mass index. Patients with lymphedema should be counseled about the negative effects of obesity on their condition. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

BACKGROUND: We aimed to identify a five-fraction schedule of adjuvant radiotherapy (radiation therapy) delivered in 1 week that is non-inferior in terms of local cancer control and is as safe as an international standard 15-fraction regimen after primary surgery for early breast cancer. Here, we present 5-year results of the FAST-Forward trial. METHODS: FAST-Forward is a multicentre, phase 3, randomised, non-inferiority trial done at 97 hospitals (47 radiotherapy centres and 50 referring hospitals) in the UK. Patients aged at least 18 years with invasive carcinoma of the breast (pT1-3, pN0-1, M0) after breast conservation surgery or mastectomy were eligible. We randomly allocated patients to either 40 Gy in 15 fractions (over 3 weeks), 27 Gy in five fractions (over 1 week), or 26 Gy in five fractions (over 1 week) to the whole breast or chest wall. Allocation was not masked because of the nature of the intervention. The primary endpoint was ipsilateral breast tumour relapse; assuming a 2% 5-year incidence for 40 Gy, non-inferiority was predefined as ≤1·6% excess for five-fraction schedules (critical hazard ratio [HR] of 1·81). Normal tissue effects were assessed by clinicians, patients, and from photographs. This trial is registered at isrctn.com, ISRCTN19906132. FINDINGS: Between Nov 24, 2011, and June 19, 2014, we recruited and obtained consent from 4096 patients from 97 UK centres, of whom 1361 were assigned to the 40 Gy schedule, 1367 to the 27 Gy schedule, and 1368 to the 26 Gy schedule. At a median follow-up of 71·5 months (IQR 71·3 to 71·7), the primary endpoint event occurred in 79 patients (31 in the 40 Gy group, 27 in the 27 Gy group, and 21 in the 26 Gy group); HRs versus 40 Gy in 15 fractions were 0·86 (95% CI 0·51 to 1·44) for 27 Gy in five fractions and 0·67 (0·38 to 1·16) for 26 Gy in five fractions. 5-year incidence of ipsilateral breast tumour relapse after 40 Gy was 2·1% (1·4 to 3·1); estimated absolute differences versus 40 Gy in 15 fractions were -0·3% (-1·0 to 0·9) for 27 Gy in five fractions (probability of incorrectly accepting an inferior five-fraction schedule: p=0·0022 vs 40 Gy in 15 fractions) and -0·7% (-1·3 to 0·3) for 26 Gy in five fractions (p=0·00019 vs 40 Gy in 15 fractions). At 5 years, any moderate or marked clinician-assessed normal tissue effects in the breast or chest wall was reported for 98 of 986 (9·9%) 40 Gy patients, 155 (15·4%) of 1005 27 Gy patients, and 121 of 1020 (11·9%) 26 Gy patients. Across all clinician assessments from 1-5 years, odds ratios versus 40 Gy in 15 fractions were 1·55 (95% CI 1·32 to 1·83, p<0·0001) for 27 Gy in five fractions and 1·12 (0·94 to 1·34, p=0·20) for 26 Gy in five fractions. Patient and photographic assessments showed higher normal tissue effect risk for 27 Gy versus 40 Gy but not for 26 Gy versus 40 Gy. INTERPRETATION: 26 Gy in five fractions over 1 week is non-inferior to the standard of 40 Gy in 15 fractions over 3 weeks for local tumour control, and is as safe in terms of normal tissue effects up to 5 years for patients prescribed adjuvant local radiotherapy after primary surgery for early-stage breast cancer.

RESUMO

Backround/Aim: Adjuvant radiotherapy in patients with cancer of the left breast may lead to impaired cardiac function. The aim of our prospective study is to evaluate (i) doses to the irradiated volume of the heart and its substructures and (ii) determine whether their correlation with changes in strain echo measurements contribute to the prediction of subclinical heart morbidity. PATIENTS AND METHODS: Twenty-five patients were enrolled in our study. We retrospectively assessed the radiation doses to the whole heart, left anterior descending artery (LAD) and left ventricle (LV). RESULTS: The mean heart dose (MHD) was 152 cGy (SD=50.56 cGy) and the range was 74-279 cGy. The LAD was the most exposed structure, with a mean dose of 448.91 cGy (SD=490.53 cGy) and range of 120-2,057cGy. Finally, the mean LV dose was 149.12 cGy (SD=69.57) with a range of 63-317 cGy. CONCLUSION: The early results of our study showed low radiation exposure of the whole heart and left ventricle, and higher exposure of the LAD. The data that will emerge from the evaluation of strain echo parameters should show whether these associations might be useful in clinical practice for the prediction of early subclinical cardiac changes.

RESUMO

BACKGROUND: Primary cervical leiomyosarcomas (CLMS) constitute 21% of all cervical sarcomas. Because of their rarity, to our knowledge, fewer than 40 cases have been reported. The aim of this study is to evaluate the clinical and surgical-pathological features, prognosis, treatment options, and survival of primary CLMS. METHODS: A systematic review of the medical literature was conducted to evaluate articles about primary CLMS. The literature was searched between 1959 and May 2019. On final evaluation, there were 29 articles (one consisted of 8 cases; one consisted of 3 cases) and 42 cases with the addition of our 4 cases. RESULTS: Age (⩾48 versus ⩽47 years) (hazard ratio.HR], 4.528; 95% confidence interval.CI], 1.550-13.227; p=0.006) and mitoses count (<10/10 high-power field [HPF] versus ⩾10/10 HPF) (HR, 3.865; 95% CI, 1.046-14.278; p=0.043) are independent prognostic factors for recurrence and age (HR, 5.318; 95% CI, 1.671-16.920; p=0.005) and hysterectomy (performed versus not performed) (HR, 4.377; 95% CI, 1.341-14.283; p=0.014) are independent prognostic factors for death because of disease on multivariate analysis. CONCLUSIONS: Information on primary CLMS is sparse and obtained from rare case reports and case series. Hysterectomy must be the first choice of treatment in these patients according to our results on multivariate analysis. The type of hysterectomy does not have an effect on oncologic outcome. Radical hysterectomy is not obligatory and more data are needed to make more accurate conclusions.

RESUMO

BACKGROUND: Whether to irradiate the tissue expander before implant exchange or to defer irradiation until after exchange in immediate, two-stage expander/implant reconstruction remains uncertain. The authors evaluated the effects of irradiation timing on complication rates and patient-reported outcomes in patients undergoing immediate expander/implant reconstruction. METHODS: Immediate expander/implant reconstruction patients undergoing postmastectomy radiation therapy at 11 Mastectomy Reconstruction Outcomes Consortium sites with demographic, clinical, and complication data were analyzed. Patient-reported outcomes were assessed with BREAST-Q, Patient-Reported Outcomes Measurement Information System, and European Organisation for Research and Treatment of Cancer Breast Cancer-Specific Quality-of-Life Questionnaire surveys preoperatively and 2 years postoperatively. Survey scores and complication rates were analyzed using bivariate comparison and multivariable regressions. RESULTS: Of 317 patients who met inclusion criteria, 237 underwent postmastectomy radiation therapy before expander/implant exchange (before-exchange cohort), and 80 did so after exchange (after-exchange cohort). Timing of radiation had no significant effect on risks of overall complications (OR, 1.25; p = 0.46), major complications (OR, 1.18; p = 0.62), or reconstructive failure (OR, 0.72; p = 0.49). Similarly, radiation timing had no significant effect on 2-year patient-reported outcomes measured by the BREAST-Q or the European Organisation for Research and Treatment of Cancer survey. Outcomes measured by the Patient-Reported Outcomes Measurement Information System showed less anxiety, fatigue, and depression in the after-exchange group. Compared with preoperative assessments, 2-year patient-reported outcomes significantly declined in both cohorts for Satisfaction with Breasts, Physical Well-Being, and Sexual Well-Being, but improved for anxiety and depression. CONCLUSIONS: Radiation timing (before or after exchange) had no significant effect on complication risks or on most patient-reported outcomes in immediate expander/implant reconstruction. Although lower levels of anxiety, depression, and fatigue were observed in the after-exchange group, these differences may not be clinically significant. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, II.

RESUMO

PURPOSE: The potential role of neoadjuvant radiation dose intensification in locally advanced rectal cancer (LARC) is still largely debated. In the present study, a comparative analysis between radiation dose intensification and conventional fractionation was performed. MATERIALS AND METHODS: In the current prospective observational study (protocol ID RT-03/2011), 56 patients diagnosed with LARC were enrolled between January 2013 and December 2016. More specifically, 25 patients underwent preoperative conventional radiation dose [i.e., 50.4 Gy in 28 fractions here defined as standard dose radiotherapy (SDR)-group 1], whereas 31 patients were candidate for radiation dose intensification (RDI) (i.e., 60 Gy in 30 fractions-group 2). The primary endpoint was the complete pathological response (pCR) rate. Secondary endpoints were postoperative complications and ChT-RT-related toxicity. RESULTS: No statistical significance was observed in pCR rate (20.8% and 22.6% in SDR and RDI group, respectively, p = 0.342). Of contrast, the RDI group showed a significantly higher primary tumor downstaging in case of T3 tumor compared to SDR group (p = 0.049). Sphincter-preserving surgery was 84% and 93.5% in SDR and RDI groups, respectively (p = 0.25). All patients had R0 margins. No surgical-related death was recorded. No statistically significant difference was observed regarding surgical complications and incomplete mesorectal excision. Acute genitourinary toxicity was significantly higher in RDI group (p = 0.015). CONCLUSIONS: The intensification of the neoadjuvant radiotherapy for LARC seems to produce a major pathological response in T3 tumors. The radiation dose intensification appears probably associated with a higher rate of genitourinary toxicity.

RESUMO

INTRODUCTION: The aim of this paper is to investigate the outcome of patients treated with mastectomy, immediate breast reconstruction (IBR) and post-mastectomy radiotherapy (PMRT) and the risk of late complications. MATERIAL AND METHOD: All patients had post-mastectomy, immediate reconstructive surgical procedure by using autologous abdominal implant; tissue expander (TE)/permanent prosthesis (PP); or even combined procedures. Adjuvant external beam radiotherapy treatment (EBRT) was delivered to the reconstructed chest wall and supraclavicular nodes, for a total dose of 50 Gy in 25 fractions. The Kaplan-Meyer analysis evaluates patients' rate of late side effects, Overall Survival (OS), Progression Free survival (PFS), Local-regional free survival (LRFS) and Metastasis Free Survival (MFS). The univariate analysis investigates the correlation between late toxicity and related factors. RESULTS: Between November 2003 and October 2016, 91 breast cancer patients were treated with IBR and PMRT. Twenty-three (25.3%) patients experimented late toxicity. Overall, 16 (17.6%) patients experienced late complications which required a surgical approach. The 1- 2- 5- years late toxicity rates were 96.6%, 87.1% and 77.9%, respectively. The type of reconstruction was not statistically related with late toxicity rate (P = 0.35). The median follow-up period was 59 months (range 6-142 months). Median OS was not reached, the 1- 2- 5-years OS rates were 100%, 95.4% and 81% respectively. CONCLUSION: This study underlines that the type of reconstruction does not influence late toxicity rate. Moreover, IBR followed by adjuvant radiotherapy, has showed acceptable late toxicity profile and no influence on OS.
