Project description:Simple Summary This multicenter retrospective study aimed to describe the outcomes of patients with endometrial cancer after central pelvic/vaginal relapse treated with radical radiotherapy (RT). We included 139 patients with a median follow-up time of 6.66 years. Patients were treated with external beam radiotherapy to elective pelvic lymph-node regions and boost to the pelvic tumor. During follow-up, 55 (39.6%) patients developed a second relapse, the majority (75%) with disease sites outside the radiation field. Risk group at primary diagnosis and type of boost administration were independent predictors of progression-free and overall survival. Five-year overall survival for the whole cohort was 68% (95% CI: 59–75%). The majority of isolated pelvic recurrences in RT-naive women with EC can be successfully salvaged by RT but survival in high-risk patients remains suboptimal. Individualizing of adjuvant treatment in first line and better treatment alternatives at relapse are important to ultimately improve survival. Abstract (1) Background: This study evaluated the clinical outcome after salvage radiotherapy for first pelvic relapse after endometrial cancer (EC). (2) Methods: This multicenter retrospective study included EC patients with first central pelvic relapse without lymph node involvement treated with curative intent. Progression-free (PFS) and overall survival (OS) were calculated with the Kaplan–Meier method and possible predictive factors for risk of relapse and mortality were identified using the Cox model. (3) Results: We included 139 patients with median EQD2 (Equivalent Dose in 2 Gy fractions) to the clinical target volume of 70.0 Gy. During follow up of median 6.66 years, 39.6% patients developed a second relapse. Risk group classification at primary diagnosis based on histology, grading and FIGO stage and how the pelvic tumor boost was administered were independently associated with PFS and OS. Five-year OS was 68% (95% CI (59–75)) for the whole cohort. Five-year OS was 88% (95% CI (75–94)), 72% (95% CI (55–84)) and 38% (95% CI (15–60)) for the stage I low-, intermediate- and high-risk group, respectively. (4) Conclusions: The majority of central pelvic recurrences in RT-naive EC women can be successfully salvaged with radiotherapy. However, survival in patients with high-risk disease remains poor and warrants a more individualized approach to optimize outcome.

Project description:ImportanceThe evidence for concurrent chemoradiotherapy (CT-RT) in International Federation of Gynecology and Obstetrics (FIGO) stage IIIB squamous cell carcinoma of the uterine cervix is not robust. This study reports the final results of a randomized clinical trial of concurrent cisplatin-based CT-RT and radiotherapy alone (RT) in women with FIGO stage IIIB squamous cell carcinoma of the uterine cervix.ObjectiveTo investigate the benefit of concurrent CT-RT in FIGO stage IIIB squamous cell carcinoma of the uterine cervix.Design, setting, and participantsThis phase 3 open-label randomized clinical trial accrued 850 women in Mumbai, India, between July 7, 2003, and September 22, 2011. Of 2121 screened, 850 women with FIGO stage IIIB squamous cell carcinoma of the uterine cervix suitable for concurrent cisplatin chemotherapy were randomly assigned to CT-RT and RT using block randomization (1:1). The data were updated for a minimum follow-up period of 5 years until December 2016. The final analyses were performed in February and March 2017. This single-institution study was conducted at a tertiary cancer center setting.InterventionsRandomization to receive RT (RT arm), comprising a combination of external beam RT (50 Gy in 25 fractions over 5 weeks) and brachytherapy, or to receive in addition to the same RT concurrent weekly cisplatin chemotherapy (40 mg/m2 per week) (CT-RT arm).Main outcomes and measuresThe primary end point was 5-year disease-free survival (DFS), defined as the time between the date of randomization and the date of any recurrence or death (whichever occurred first) in the intent-to-treat population.ResultsThis trial included 424 women assigned to CT-RT (mean [SD] age, 49.4 [7.9] years) and 426 women assigned to RT (mean [SD] age, 49.3 [7.9] years). At a median follow-up of 88 months (interquartile range, 61.3-113.1 months), there were 222 recurrences and 213 deaths in the CT-RT arm and 252 recurrences and 243 deaths in the RT arm. The 5-year DFS was significantly higher in the CT-RT arm (52.3%; 95% CI, 52.2%-52.4%) compared with the RT arm (43.8%; 95% CI, 43.7%-43.9%), with a hazard ratio for relapse or death of 0.81 (95% CI, 0.68-0.98) (P = .03). Similarly, the 5-year overall survival (OS) was significantly higher in the CT-RT arm (54.0%; 95% CI, 53.9%-54.1%) compared with the RT arm (46.0%; 95% CI, 45.9%-46.1%), with a hazard ratio for death of 0.82 (95% CI, 0.68-0.98; P = .04). After adjusting for prognostic factors, CT-RT continued to be significantly superior to RT for DFS and OS. There was a higher incidence of acute hematological adverse effects in the CT-RT arm.Conclusions and relevanceChemoradiotherapy using weekly cisplatin results in significantly better DFS and OS compared with RT in women with stage IIIB squamous cell carcinoma of the uterine cervix. This study provides level 1 evidence in the largest clinical trial reported so far in favor of concurrent weekly cisplatin chemotherapy in this setting.Trial registrationclinicaltrials.gov Identifier: NCT00193791.

Project description:BACKGROUND:To assess late toxicity, quality of life and oncological outcome after consolidative whole abdominal radiotherapy (WART) following cytoreductive surgery and carboplatin/paclitaxel chemotherapy in high risk patients with advanced ovarian cancer FIGO stage III using IMRT (Intensity modulated radiation therapy). METHODS:The OVAR-IMRT-02 study is a multi-center single-arm phase-II-trial. Twenty patients with optimally debulked ovarian cancer stage FIGO III with complete remission after chemotherapy were treated with intensity modulated WART. A total dose of 30?Gy in 20 fractions was applied to the entire peritoneal cavity. Primary endpoint was treatment tolerability; secondary objectives were acute and chronic toxicities, quality of life, rates of therapy disruption/abortion, progression-free survival (PFS) and overall survival (OS). RESULTS:All patients completed treatment and 10/20 patients (50%) reached the final study follow-up of 36?months. Late side effects consisted of °1-°2 lower limb edema (44.5%), with one patient (5.6%) showing °3 edema. Three patients (16.7%) showed elevated gamma-Glutamyltransferase. There were no severe late side effects regarding renal or hepatic function or any gastrointestinal toxicity greater than °2. During WART, mean global health status decreased by 18.1 points (95%-CI: 7.1-29.0), but completely normalized after 6?months. The same trend was observed for the function scale scores. Kaplan-Meier-estimated 1-, 2- and 3-year PFS was 74, 51 and 40%, respectively. 1-, 2- and 3-year OS was 89, 83 and 83%, respectively. CONCLUSIONS:Intensity modulated WART after aggressive surgery and carboplatin/paclitaxel chemotherapy is associated with an acceptable risk of acute and late toxicity and minor impact on long-term quality of life. Together with the promising results for PFS and OS, intensity modulated WART could offer a new therapeutic option for consolidation treatment of patients with advanced ovarian cancer. TRIAL REGISTRATION:The study is registered with ClinicalTrials.gov ( NCT01180504 ). Registered 12 August 2010 - retrospectively registered.

Project description:ObjectiveTo compare the prognostic value of International Federation of Gynecology and Obstetrics (FIGO) 2009 and 2018 staging systems in surgical patients with small cell neuroendocrine carcinoma of the cervix (SCNEC).MethodsWe re-staged 64 surgical IB-IIA (FIGO 2009) SCNEC patients according to the FIGO 2018 system and refined stage IIIC of FIGO 2018 based on tumor local invasion. The prognostic factors were analyzed, and the advantages of FIGO 2018 were compared with 2009.ResultsThe 5-year overall survival rate (OS) was 78.5% for stage I and 22.2% for stage II (FIGO 2009). In FIGO 2018, there was no difference between stage I and II, and the 5-year OS was 74.1%, 60.2%, and 0% for stage I/II, IIIC1, and IIIC2. After combining stage IIIC with the local invasion stage (T1 was limited to the cervix and vagina; T2 involved the parametrium; T3 involved the pelvic or abdominal cavity), the 5-year OS for stage IIICT1, IIICT2, and IIICT3 was 83.3%, 30.0%, and 0%, respectively.ConclusionsFor stage II SCNEC patients, FIGO 2009 underestimated the prognosis, while FIGO 2018 was more accurate. For stage IIIC, FIGO 2018 might be more individualized and accurate after combining stage IIIC with tumor local invasion.

Project description:To evaluate the association between adjuvant chemotherapy and clinical outcomes in patients with stage IC adult granulosa cell tumor (AGCT).We performed a retrospective study of patients with stage IC AGCT diagnosed at our hospital from January 1985 to September 2015. We analyzed descriptive statistics, and performed univariate and multivariate and Kaplan-Meier survival analyses.Sixty stage IC AGCT patients were identified, including 28 in the no adjuvant chemotherapy group (NACG) and 32 in the adjuvant chemotherapy group (ACG). The median follow-up time was 88 months (range: 9-334 months). Sixteen patients developed recurrences, including nine in the NACG and seven in the ACG groups. Univariate analysis identified incomplete surgical staging and initial treatment place as associated with disease-free survival (DFS) (P?=?0.003 and 0.038, respectively). Incomplete surgical staging remained a risk factor for recurrence in multivariate analysis (hazard ratio (HR)?=?3.883, 95% confidence interval (CI): 1.123-13.430, P?=?0.032). The 5-year DFS rates in the NACG and ACG groups were 76.3% and 87.5% respectively (P?=?0.197). Adjuvant chemotherapy was thus not associated with improved DFS. Furthermore, the number of chemotherapy cycles was not associated with recurrence rate (?3 cycles vs. >?3 cycles, HR?=?0.613, 95% CI: 0.112-3.351, P?=?0.572).Administration of adjuvant chemotherapy does not improve DFS in patients with stage IC AGCT. Further studies with larger samples involving multi-institutional collaboration are needed to validate new treatment regimens for this disease.

Project description:BackgroundData on efficacy of adjuvant therapy for surgically resected small cell lung cancer are scant. This study was determined to reveal the survival benefits of different adjuvant treatment modalities for limited-stage small cell lung cancer patients following surgical resection.MethodsData of patients with histologically confirmed small cell lung cancer after surgical resection were collected from November 2006 to June 2019. Survival analyses were calculated by Kaplan-Meier method, with log-rank test to evaluate statistical significance. Prognostic factors were identified by multivariate analysis using cox proportional hazards model. Further survival analysis and cox regression analysis stratified by clinicopathologic features were conducted to evaluate the survival benefits of different adjuvant treatment modalities.ResultsIn total, 153 out of 157 patients were analyzed. Multivariate analysis showed male sex, lymph node metastasis, residual tumor, VPI and non-adjuvant therapy were independently associated with poor prognosis. Subgroup analyses revealed both adjuvant chemotherapy and adjuvant chemoradiotherapy were significantly associated with superior survival for stage pT2-4 (HR=0.176, 95%CI:0.053-0.578, p=0.004; and HR=0.115, 95%CI:0.033-0.405, p=0.001) and pure SCLC patients (HR=0.182, 95%CI:0.067-0.494, p=0.001; and HR=0.181, 95%CI:0.071-0.465, p<0.001). For pN0 patients, adjuvant chemotherapy was associated with better survival (HR=0.219, 95%CI:0.054-0.891, p=0.034), while adjuvant chemoradiotherapy was associated with improved survival for pN+ patients (HR=0.324, 95%CI:0.138-0.760, p=0.010).ConclusionsFor patients without pathologic lymph node metastasis, there is a survival benefit with adjuvant chemotherapy. However, for patients with pathologic lymph node metastasis, adjuvant chemoradiotherapy might achieve a significant survival benefit. Further prospective studies are needed to validate the results.

Project description:IntroductionFew recent studies have examined patient reported outcomes (PROs) during pre- or post-operative radiation therapy (RT) for soft tissue sarcoma (STS), and none have used PROMIS. This study aims to examine PROMIS scores across peri-operative time points for patients receiving pre- or post-operative RT.MethodsAnxiety, depression, pain interference, and physical function PROMIS domains were collected at the pre-operative (1), immediate post-operative (2), and post-treatment completion (3) timepoints for patients undergoing surgery and either pre-operative or post-operative RT. Median scores were compared between groups using the Kruskal-Wallis test. The reliable change index was used to determine minimum important change in PROMIS scores and to compare scores between timepoints.Results95 patients were included (19 pre-operative, 76 post-operative). Both groups had significant decreases in function during treatment. Patients with wound complications were more likely to have significant increases in anxiety (36.4% vs. 8.3%; p = 0.020) and decreases in physical function (57.1% vs. 16.2%; p = 0.011) independent of RT timing.ConclusionsThis study demonstrates minimum significant change thresholds to detect PROMIS changes in STS patients undergoing pre- and post-operative radiotherapy. As expected, more patients with pre-operative RT than post-operative RT had wound complications (p = 0.06), but patients with complications in both groups had worse anxiety and function at the completion of treatment compared with those that did not. The association of wound complications with worse anxiety and physical function at completion of treatment should be considered when making individualized treatment recommendations regarding the timing of RT.

Project description:BackgroundIn most guidelines, upper rectal cancers (URC) are not recommended to take neoadjuvant or adjuvant radiation. However, the definitions of URC vary greatly. Five definitions had been commonly used to define URC: 1) >10 cm from the anal verge by MRI; 2) >12 cm from the anal verge by MRI; 3) >10 cm from the anal verge by colonoscopy; 4) >12 cm from the anal verge by colonoscopy; 5) above the anterior peritoneal reflection (APR). We hypothesized that the fifth definition is optimal to identify patients with rectal cancer to avoid adjuvant radiation.MethodsThe data of stage II/III rectal cancer patients who underwent radical surgery without preoperative chemoradiotherapy were retrospectively reviewed. The height of the APR was measured, and compared with the tumor height measured by digital rectal examination (DRE), MRI and colonoscopy. The five definitions were compared in terms of prediction of local recurrence, survival, and percentages of patients requiring radiation.ResultsA total of 576 patients were included, with the intraoperative location of 222 and 354 tumors being above and straddle/below the APR, respectively. The median distance of the APR from anal verge (height of APR) as measured by MRI was 8.7 (range: 4.5-14.3) cm. The height of APR positively correlated with body height (r=0.862, P<0.001). The accuracy of the MRI in determining the tumor location with respect to the APR was 92.1%. Rectal cancer above the APR had a significantly lower incidence of local recurrence than those straddle/below the APR (P=0.042). For those above the APR, there was no significant difference in local recurrence between the radiation and no-radiation group. Multivariate analyses showed that tumor location regarding APR was an independent risk factor for LRFS. Tumor height as measured by DRE, MRI and colonoscopy were not related with survival outcomes. Fewer rectal cancer patients required adjuvant radiation using the definition by the APR, compared with other four definitions based on a numerical tumor height measured by MRI and colonoscopy.ConclusionsThe definition of URC as rectal tumor above the APR, might be the optimal definition to select patients with stage II/III rectal cancer to avoid postoperative adjuvant radiation.

Project description:Background and objectives: The histological classification and staging of thymic tumors remains a matter of debate. The correlation of computed tomography (CT) parameters with tumor histology and stage also still has to be completely assessed. The aim of this study was therefore to analyze the correlation of radiological parameters with histological and staging classifications of thymomas evaluating their prognostic role. Methods: Data of 50 patients with thymoma submitted to a complete surgical treatment between 2005 and 2015 were retrospectively analyzed. Tumors were classified according to the WHO and Suster and Moran (S&M) histological classifications and to the Masaoka-Koga and tumor, node and metastases (TNM) staging systems. The correlation of CT features with histology and stage and the prognostic role of histopathological and radiological features were assessed. Results: Five-year overall (OS) and disease-free survival (DFS) were 90.3% and 81.1%, respectively. A significant correlation of DFS with the Masaoka-Koga (p = 0.001) and TNM staging systems (p = 0.002) and with the S&M (p = 0.02) and WHO histological classifications (p = 0.04) was observed. CT scan features correlated with tumor stage, histology and prognosis. Moderately differentiated tumors (WHO B3) had a significantly higher incidence of irregular shape and contours (p = 0.002 and p = 0.001, respectively) and pericardial contact (p = 0.036). A larger tumor volume (p = 0.03) and a greater length of pleural contact (p = 0.04) adversely influenced DFS. The presence of pleural (p < 0.001) or lung invasion (p = 0.02) and of pleural effusion (p = 0.004) was associated with a significantly worse OS. Conclusions: Pre-operative CT scan parameters correlate with stage and histology, and have a prognostic role in surgically treated thymomas.

Project description:ObjectiveTo evaluate the clinical role of adjuvant chemotherapy (AC) in FIGO stage IB-IIA cervical cancer patients.Study designA cohort of 262 patients with cervical cancer who received radical hysterectomy (RH) and adjuvant therapy at Asan Medical Center between 1992 and 2012 was enrolled. In this cohort, 85 patients received adjuvant chemotherapy (AC), and 177 received adjuvant radiotherapy or concurrent chemoradiation therapy (AR). Oncologic outcomes and adverse events in both treatment arms were compared using weighted Cox proportional hazards regression models with inverse-probability-of-treatment weighting (IPTW) to reduce the impact of treatment selection bias and potential confounding factors.ResultsDuring a 46.8-month median follow-up duration, 39 patients (14.9%) had recurrences, and 18 patients (6.9%) died of disease. In multivariate analysis, the hazard ratio (HR) for recurrence and death was not significantly different in patients in either treatment arm (p=0.62 and 0.12, respectively). Also, after IPTW matching, the HR for recurrence did not significantly differ between the arms (HR 1.57, 95% CI 0.68-3.62, p=0.29). Similarly, disease-free survival and overall survival were not significantly different between the arms (p=0.47 and 0.13, respectively). In addition, patients with AC had a much lower prevalence of long-term complications (lymphedema: n=8 (9.4%) vs. 46 (26.0%), p=0.03; ureteral stricture: n=0 vs. 9 (6.2%), p=0.05).ConclusionPatients with FIGO stage IB-IIA cervical cancer can benefit from AC after RH with fewer long-term complications and non-inferior therapeutic effect to AR. Chemotherapy may therefore be an alternative adjuvant treatment option for cervical cancer, particularly in younger patients.
