Risk Factors For Recurrence

AbstractThis study evaluated the influence of positive peritoneal cytology (PPC) on the prognosis of patients with stage IA endometrial cancer, and the usefulness of adjuvant chemotherapy in their treatment. We retrospectively analyzed the data of patients with stage IA endometrial cancer admitted in our hospital between 2005 and 2015. Among 989 patients who underwent peritoneal cytology, 135 (13.7%) had PPC. Multivariate analysis extracted several independent risk factors for recurrence in stage IA patients, including those with PPC. Adjuvant chemotherapy did not cause a significant difference in the 5-year relapse-free survival rate in patients with PPC (p = 0.78). Similarly, the 5-year recurrence-free survival rate with or without chemotherapy was not different among type II cancer patients (p = 0.11). However, the baseline risk of 5-year relapse-free survival without chemotherapy in patients with PPC and type II was very low (66.7%). While PPC was an independent risk factor for recurrence in stage IA endometrial cancer, adjuvant chemotherapy did not influence the survival rate in patients with PPC. While it is controversial whether adjuvant chemotherapy should be administered in stage IA uterine cancer with only PPC as a prognostic factor, it should be considered for early-stage patients who have multiple risk factors for recurrence.

End Point

Purpose The first planned interim analysis (median follow-up, 3 years) of the Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer confirmed that the oral fluoropyrimidine derivative S-1 significantly improved overall survival, the primary end point. The results were therefore opened at the recommendation of an independent data and safety monitoring committee. We report 5-year follow-up data on patients enrolled onto the ACTS-GC study. Patients and Methods Patients with histologically confirmed stage II or III gastric cancer who underwent gastrectomy with D2 lymphadenectomy were randomly assigned to receive S-1 after surgery or surgery only. S-1 (80 to 120 mg per day) was given for 4 weeks, followed by 2 weeks of rest. This 6-week cycle was repeated for 1 year. The primary end point was overall survival, and the secondary end points were relapse-free survival and safety. Results The overall survival rate at 5 years was 71.7% in the S-1 group and 61.1% in the surgery-only group (hazard ratio [HR], 0.669; 95% CI, 0.540 to 0.828). The relapse-free survival rate at 5 years was 65.4% in the S-1 group and 53.1% in the surgery-only group (HR, 0.653; 95% CI, 0.537 to 0.793). Subgroup analyses according to principal demographic factors such as sex, age, disease stage, and histologic type showed no interaction between treatment and any characteristic. Conclusion On the basis of 5-year follow-up data, postoperative adjuvant therapy with S-1 was confirmed to improve overall survival and relapse-free survival in patients with stage II or III gastric cancer who had undergone D2 gastrectomy.

114 Background: Based on the results of ACTS-GC, oral administration of S-1 for 1 year is considered standard postoperative adjuvant chemotherapy for gastric cancer in Japan. However, the 1-year treatment completion rate was only 65.8%, and completion of the treatment is a problem to be solved. On the other hand, we experienced in clinical practice that the alternate-day administration of S-1 reduced adverse effects and was tolerable for advanced gastric cancer patients unwilling to continue the standard daily administration. We therefore conducted a multi-center cooperative prospective study to compare daily with alternate-day administration of S-1 as postoperative adjuvant therapy for gastric cancer. Methods: Patients with Stage II or III gastric cancer who underwent curative surgery were randomly assigned to receive standard daily administration (group A: S-1 80-120 mg/day according to BSA, days 1 to 28, every 6weeks, for 1 year) or alternate-day administration of S-1 (group B: S-1 80-120 mg/day according to BSA, every other day, for 15 months). The primary endpoints were treatment completion rate and relative dose intensity. Secondary endpoints were safety, overall survival, and relapse-free survival. Results: A total of 73 patients were enrolled. As of August 30, 2011 analysis of the compliance data of 62 cases had been completed. The results showed a treatment completion rate of 74.2% in group A and 93.5% in group B and relative dose intensity of 72.1% in group A and 85.6% in group B, and compliance tended to be better in group B. Assessment of survival time showed a median follow-up time of 545 days, a 1-year survival rate of 93.8% in group A and 96.9% in group B and 1-year relapse-free survival rate of 79.5% in group A and 90.7% in group B. Digestive system adverse events were less frequent in group B than in group A. Conclusions: We will report the data from the final analysis at this meeting. The current data show improved compliance and mitigation of adverse effects with alternate-day administration of S-1, and it appears to be a more sustainable option for adjuvant chemotherapy for Stage II and III gastric cancer.

Objective:To assess the impact of adjuvant chemotherapy in early surgically staged type II endometrial cancer (serous [S], clear cell carcinoma [CC]) and carcinosarcomas (CS) on recurrence and survival.Materials and Methods:Patients diagnosed with stages I-II S-CC and CS after comprehensive surgical staging were retrospectively collected. Surgical staging was defined as pelvic lymphadenectomy of more than 11 nodes harvested and exploration of the upper abdomen, with our without omentectomy. Groups with (group A) and without (group B) platinum-based chemotherapy were compared.Results:We identified 69 patients with a mean age of 66 years (range, 48-88 years). Both groups showed similar baseline characteristics. Group A consisted of 34 patients (23 S-CC, 11 CS) with 10 (29%) recurrences outside the pelvis (7 S-CC, 3 CS). Group B included 35 patients (28 S-CC, 7 CS) of which 10 (29%) developed recurrence outside the pelvis (7 S-CC, 3 CS). The median recurrence-free survival was 22 months (range, 13-51 months) for group A versus 10 months (range, 1-59 months) for group B (P= 0.437). Five patients (15%) of group A and 9 (26%) of group B died of disease after a median follow-up of 29 months (range, 20-59 months) and 17 months (range, 4-64 months), respectively (P= 0.168).Conclusion:Recurrences in early-stage type II endometrial cancer and carcinosarcomas occur irrespective of adjuvant chemotherapy, but recurrence-free survival is prolonged when adjuvant chemotherapy is administered. Only prospective randomized intergroup trials can address the benefit of adjuvant chemotherapy in early-stage high-risk endometrial cancer.

ObjectiveThe objective of this study was to elucidate factors that affect prognosis in patients with stage I endometrial cancer.MethodsThe study group comprised 265 patients with stage I endometrial cancer treated surgically at either of our facilities between January 1998 and December 2010 (238 patients with negative peritoneal cytology and 27 patients with positive peritoneal cytology). Progression-free survivals were evaluated between the 2 groups, and multivariate analysis was conducted with correlation factors including positive peritoneal cytology, vessel permeation, lymph node dissection, histologic diagnosis, age at diagnosis, adjuvant chemotherapy, and the depth of myometrial invasion.ResultsDisease-free survival was significantly poorer for patients with positive peritoneal cytology than those with negative peritoneal cytology on stage I disease (P = 0.000). The stratified log-rank test with vessel permeation shows the similar results. By univariate Cox model, positive peritoneal cytology, vessel permeation, and systemic lymph node dissection at surgery are significant factors on stage I endometrial cancer.ConclusionsAlthough this is a small-scale preliminary study with adjustment of other factors, positive peritoneal cytology can contribute to the risk of progression-free survival in patients with stage I endometrial cancer.

Abstract Background There is uncertainty surrounding the prognostic value of peritoneal cytology in low-risk endometrial cancer, especially in laparoscopic surgery. The objective of this retrospective study is to determine the prognostic significance of positive peritoneal cytology among patients with low-risk endometrial cancer and to compare it between laparoscopic surgery and conventional laparotomy. Methods From August 2008 to December 2019, all cases of pathologically confirmed stage IA grade 1 or 2 endometrial cancer were reviewed at Osaka Medical College. Statistical analyses used the Chi-square test and the Kaplan–Meier log rank. Results A total of 478 patients were identified: 438 with negative peritoneal cytology (232 who underwent laparotomy and 206 who undertook laparoscopic surgery) and 40 with positive peritoneal cytology (20 who underwent laparotomy and 20 who received laparoscopic surgery). Survival was significantly worse among patients with positive peritoneal cytology compared to patients with negative peritoneal cytology. However, there was no significant difference among patients with negative or positive peritoneal cytology between laparoscopic surgery and laparotomy. Conclusion This retrospective study suggests that, while peritoneal cytology is an independent risk factor in patients with low-risk endometrial cancer, laparoscopic surgery does not influence the survival outcome when compared to laparotomy.

Purpose: To evaluate the survival benefit of adjuvant chemotherapy after curative resection in serosa-negative gastric cancer patients (excluding patients who were T1N0), we conducted a multicenter phase III clinical trial in which 13 cancer centers in Japan participated. Patients and Methods: From January 1993 to December 1994, 252 patients were enrolled into the study and allocated randomly to adjuvant chemotherapy or surgery alone. The chemotherapy comprised intravenous mitomycin 1.33 mg/m2, fluorouracil (FU) 166.7 mg/m2, and cytarabine 13.3 mg/m2 twice weekly for the first 3 weeks after surgery, and oral FU 134 mg/m2 daily for the next 18 months for a total dose of 67 g/m2. The primary end point was relapse-free survival. Overall survival and the site of recurrence were secondary end points. Results: Ninety-eight percent of patients underwent gastrectomy with D2 or greater lymph node dissection. There were no treatment-related deaths and few serious adverse events. There was no significant difference in relapse-free and overall survival between the arms (5-year relapse-free survival 88.8% chemotherapy v 83.7% surgery alone; P = .14 and 5-year survival 91.2% chemotherapy v 86.1% surgery alone; P = .13, respectively). Nine patients (7.1%) in the chemotherapy arm and 17 patients (13.8%) in the surgery-alone arm had cancer recurrence. Conclusion: There was no statistically significant relapse-free or overall survival benefit with this adjuvant chemotherapy for patients with macroscopically serosa-negative gastric cancer after curative resection, and there was no statistical difference between the two arms relating to the types of cancer recurrence. We do not recommend adjuvant chemotherapy with this regimen for this population in clinical practice.

Background There is no standard adjuvant chemotherapy to prevent recurrent cholangiocarcinoma (CCA), a rare cancer with poor prognosis. We assessed the efficacy and safety of GEMOX on intrahepatic and hilar CCA with high-risk factors after curative surgery. Patients and Methods Twenty two patients (mean age: 57 years old) with CCA received 6 cycles of GEMOX: gemcitabine 1,000 mg/m2 on day 1 and oxaliplatin 85 mg/m2 on day 2, q3w after a curative surgery. Results All patients completed 6 cycles of GEMOX. EGFR membranous expression was present in 20 CCA. The 5-year survival rate was 56% (CI 95%: 25.7–85.4); 2-year disease free survival rate was 28% (CI 95%: 3.4–52.6). Median time to progression was 15 months. The rate of recurrence after surgery and chemotherapy was 63% (14/22). Two patients died of disease progression. Twelve patients received cetuximab/GEMOX at the time of relapse. Six died after 12 months (9–48 months), three are still alive suggesting a clinical applicability of EGFR inhibitors in CCA. Conclusion Adjuvant chemotherapy with GEMOX alone seems ineffective in intrahepatic and hilar CCA with a high risk of relapse. Additional studies including targeted therapies to circumvent such poor chemosensitivity are needed.
