Abstract Background and purpose Concurrent chemoradiotherapy is the established treatment for locally advanced nasopharyngeal carcinoma (NPC). However, there is no evidence supporting routine adjuvant chemotherapy. We aimed to demonstrate the effect of adjuvant chemotherapy on survival and distant metastasis in high-risk N3 NPC patients. Materials and methods We linked the Taiwan Cancer Registry and Cause of Death database to obtain data. Clinical N3 NPC patients were divided as those receiving definitive concurrent chemoradiotherapy (CCRT) with adjuvant 5-fluorouracil and platinum (PF) chemotherapy and those receiving no chemotherapy after CCRT. Patients receiving neoadjuvant chemotherapy were excluded. We compared overall survival, disease-free survival, local control, and distant metastasis in both groups using Cox proportional hazards regression analysis. Results We included 431 patients (152 and 279 patients in the adjuvant PF and observation groups, respectively). Median follow-up was 4.3 years. The 5-year overall survival were 69.1% and 57.4% in the adjuvant PF chemotherapy and observation groups, respectively (p = 0.02). Adjuvant PF chemotherapy was associated with a lower risk of death (hazard ratio [HR] = 0.61, 95% confidence interval [CI]: 0.43–0.84; p = 0.003), even after adjusting for baseline prognostic factors (HR = 0.61, 95% CI: 0.43–0.86; p = 0.005). Distant metastasis-free survival at 12 months was higher in the adjuvant PF chemotherapy group than in the observation group (98% vs 84.8%; p < 0.001). After adjusting for baseline prognostic factors, adjuvant PF chemotherapy was associated with freedom from distant metastasis (HR = 0.11, 95% CI: 0.02–0.46; p = 0.003). Conclusion Prospective evaluation of adjuvant PF chemotherapy in N3 NPC patients treated with definitive CCRT is warranted because adjuvant PF chemotherapy was associated with improved overall survival and decreased risk of distant metastasis.

The objective of this study was to evaluate the influence of cisplatin dose upon 3-year overall and disease-free survival rate of patients with advanced cervical cancer treated with concurrent chemoradiotherapy with weekly cisplatin. Seventy-three patients with stage IIB – IVA cervical carcinoma were treated with pelvic (or pelvic + paraaortic) externalbeam radiotherapy, high-dose rate brachytherapy and concomitant chemotherapy with weekly cisplatin of 40 mg/m2 in the time period form January 2000 to December 2006 at our department. The 3-year overall survival and disease-free suvival rates were evaluated with regard to the number of cisplatin cycles applied during the external radiotherapy. Only twentyeight patients received the intended five doses of chemotherapy. The most frequent cause of chemotherapy delay was the acute hematological toxicity with leukopenia. The 3-year overall survival was 71 % and the 3-year disease-free survival was 61 %. Survival analyses didn’t prove a statistically significant influence of cisplatin dose upon 3-year survival in cervical carcinoma patients treated by exclusive chemoradiation with weekly cisplatin.

e11628 Background: Neoadjuvant chemotherapy is one of the standard treatment options for patients with locally advanced breast cancer for twenty five years. In this study, we evaluate results of neoadjuvant chemotherapy in breast cancer patients. Methods: We retrospectively analyzed 68 patients with locally advanced breast cancer. Anthracycline/taxane-based chemotherapy regimens were prescribed mostly for neoadjuvant chemotherapy. Before chemotherapy was given, patients were examined for distant metastasis by radiologic methods thereafter if patient had distant metastasis, they were excluded. Patients with breast cancer received neoadjuvant chemotherapy were analyzed according to age, menopausal status, type of surgery, response to the treatment, histopathological properties and survival. After 3 to 6 cycle of chemotherapy patients were reevaluated by clinically and radiologically for response. Surgery was performed for appropriate patient thereafter adjuvant locoregional and systemic chemotherapy were continued. Results: Median age was 47 (29–43) years. 17,6 % of them were younger than 35 years and 42,6 % were premenopausal. Median follow-up time was 19 month. After 3 to 6 cycle of neoadjuvant chemotherapy 64 of patients responded to therapy (94,1 %). Breast conserving surgery was performed for 15,6 % patients. In histopathologic analysis most of patients were invasive ductal carcinoma and there was lymph node invasion for 84,9 %. Estrogen and progesterone receptor status were negative for 18,6 % of patients and cerbB2 was positive for 14,8 % of patients. Median disease free survival time was 44 month (SE: 9; 95% CI: 25–62) but median overall survival time could not be reached. Three years disease free survival rate and overall survival rate were 55,3% and 90,1% respectively. According to Cox regression analyses; we did not find any demographic and pathologic characteristic of breast cancer that is related to prognosis. Conclusions: In recent years neoadjuvant chemotherapy in breast cancer is increasingly being used for early stage disease. Further study will be facilitated establishment of guidelines for preselecting patients for neoadjuvant chemotherapy and will provide beneficial effect on treatment option and survival. No significant financial relationships to disclose.

Background Locally advanced colon cancer (LACC) is associated with surgical challenges during R0 resection, increased postoperative complications, and unfavorable treatment outcomes. Neoadjuvant concurrent chemoradiotherapy followed by surgical resection is an effective treatment strategy that can increase the complete surgical resection rate and improve the patient survival rate. This study investigated the efficacy and toxicity of concurrent chemoradiotherapy in patients with LACC as well as the prognosis and long-term clinical outcomes of these patients. Materials From January 2012 to July 2020, we retrospectively reviewed the real-world data of 75 patients with LACC who received neoadjuvant concurrent chemoradiotherapy. The chemotherapy regimen consisted of folinic acid, 5-fluorouracil, and oxaliplatin (FOLFOX). The following data were obtained from medical records: patients’ characteristics, pathologic results, toxicity, and long-term oncologic outcome. Results Of the 75 patients, 13 (17.3%) had pathologic complete responses. Hematologic adverse effects were the most common (grade 1 anemia: 80.0% and leukopenia: 82.7%). Conversely, grade 2 or 3 adverse effects were relatively uncommon (<10%). Pathologic N downstaging, ypT0, and pathologic complete responses were significant prognostic factors for patient survival. Multivariate analysis revealed that pathologic N downstaging was an independent predictor of patients’ overall survival (P = 0.019). The estimated 5-year overall and disease-free survival rates were 68.6% and 50.6%, and the medians of overall and disease-free survival periods were 72.3 and 58.7 months, respectively. Moreover, patients with pathologic complete responses had improved overall survival (P = 0.039) and an improved local recurrence control rate (P = 0.042) but an unfavorable distant metastasis control rate (P = 0.666) in the long-term follow-up. Conclusion The long-term oncologic outcome of patients with LACC following concurrent chemoradiotherapy is acceptable, and the adverse effects seem to be tolerable. Pathologic N downstaging was an independent prognostic factor for patients’ overall survival. However, a large prospective, randomized control study is required to confirm the current results.

Abstract Objective: This study aimed to explore the clinical value of adjuvant chemotherapy (ACT) in locoregionally advanced nasopharyngeal carcinoma (LANC) following concurrent chemoradiotherapy (CCRT) and induction chemotherapy (ICT).Methods: We included 839 newly diagnosed LANC patients in the study. ICT plus CCRT (ICT+CCRT group) was administered to 443 patients and 396 patients who received ACT after receiving ICT plus CCRT (ICT+CCRT+ACT group). Univariate and multivariate Cox regression analyses were carried out in this study. Furthermore, to balance the study and control groups, propensity score matching (PSM) was applied.Results: 373 pairs of LANC patients were obtained after the PSM analysis. We found that ACT following ICT+CCRT had no significant effect on improving the survival of LANC patients. By further exploring the ICT+CCRT+ACT regimen, we excluded N0-1-positive patients and performed PSM in the ICT+CCRT and ICT+CCRT+ACT groups again. Each group consisted of 237 patients. Kaplan-Meier analysis revealed that there was a difference between the ICT+CCRT and ICT+CCRT+ACT groups in terms of the 5-year overall survival (OS) (78.9% vs. 85.0%, P = 0.034), disease-free survival (DFS) (73.4% vs. 81.7%, P = 0.029), and distant metastasis-free survival (DMFS) (84.9% vs. 76.0%, P = 0.019). In addition, the ICT+CCRT+ACT group had a higher incidence of grade 3-4 acute leukocytopenia/neutropenia.Conclusion: Compared with ICT+CCRT, ACT following ICT plus CCRT can reduce distant metastasis of N2-3-positive LANC and improve the OS and DFS of these patients, thus demonstrating higher clinical feasibility.

IntroductionStandard treatment for locally advanced cervical cancer (LACC) includes concomitant chemoradiotherapy (CRT) that typically controls localized disease. However, most patients develop distant metastasis, ultimately leading to death.ObjectiveTo determine the role of adjuvant carboplatin and paclitaxel for clinical outcomes in patients with LACC.MethodsBetween 2010 and 2017, 109 patients with LACC were retrospectively evaluated. All patients received cisplatin (40 mg/m2) with concurrent external-beam radiotherapy (up to 50.4 Gy), followed by intra-cavitary brachytherapy. Forty-six of 109 patients received a median of six cycles (range 3–6 cycles) of adjuvant chemotherapy consisting of paclitaxel (175 mg/m2) and carboplatin (CRT + chemotherapy group; area under the curve 5). The remaining 63 patients did not receive adjuvant chemotherapy (CRT group).ResultsDisease-free survival and overall survival after a median follow-up of 24.5 months (range 2.6–94.75 months) were 93.5% and 95.7% and 69.8% and 82.5 % for the CRT + chemotherapy and CRT groups, respectively (p = 0.001, p = 0.012, respectively). No acute grade 3/4 gastrointestinal or genitourinary toxicities were seen during CRT. During adjuvant chemotherapy, the most troublesome side effects were hematologic and neurologic toxicities; however, most were manageable. No chronic grade 3/4 genitourinary toxicities were seen.DiscussionAdjuvant chemotherapy in patients with LACC significantly improved both disease-free survival and overall survival without increasing unmanageable toxicity. Future larger prospective trials are warranted to verify these findings.

4126 Background: Previous reports have suggested that mucinous colorectal adenocarcinomas have a poorer prognosis than nonmucinous colorectal adenocarcinomas. This retrospective analysis was conducted to explore whether mucinous carcinoma (MC) is associated with a worse prognosis than nonmucinous carcinoma (NMC) for patients with Dukes B2 and C radically resected colon cancer. Methods: We investigated 1,006 unselected patients who underwent curative surgery for sporadic colon cancer and followed up at six Oncology Department between 1998 and 2006. Univariate and multivariate analyses were performed to determine prognostic factors of survival. Results: MC accounted for 17.9% (n=180) of all colon carcinomas. Patient characteristics were as follows. MC: M/F 104/76; median age, 68 (range, 28–97); pT1/2/3/4, 1/4/153/22; Dukes B2/C 98/82; invasion 26 (14%); ≥12 examined lymph nodes, 115 (64%); adjuvant chemotherapy, 110 (61%). NMC: M/F 445/381; median age, 68 (range, 29–95); pT1/2/3/4, 9/51/715/51; Dukes B2/C 384/442; invasion 199 (24%); ≥12 examined lymph nodes, 499 (60%); adjuvant chemotherapy, 545 (66%). MC were more frequently located in the proximal colon (54.4% versus 34.6% for NMC; p<0.001). No difference between MC and NMC in disease-free survival (hazard ratio, HR 1.01; 95% CI, 0.76–1.36; p=0.92) and overall survival (HR 1.05; 95% CI, 0.74–1.49; p=0.78) was found. After stratification by stage of disease, MC and NMC had no statistically significant difference in 5-year disease-free survival (Dukes B2: 79.1% and 78.1%, respectively, p=0.86; Dukes C: 53.8% and 56.2%, respectively, p=0.58) and overall survival (Dukes B2: 84.2% and 85.5%, respectively, p=0.80; Dukes C: 68.0% and 67.3% p=0.52). Multivariate analysis using the Cox proportional hazards model showed that the clinically significant prognostic factors were stage at diagnosis (p<0.0001), grading (p<0.0001), and number of lymph node examined (p=0.0002) in the specimen. Conclusions: In this preliminary analysis, patients with mucinous histology who underwent surgery with curative intent for stage Dukes B2 and C colon cancer had similar prognosis compared to NMC. No significant financial relationships to disclose.

Background: This study aims to identify the prognostic factors in Stage IIIA non-small cell lung cancer and to investigate whether there was a significant difference in terms of overall survival and disease-free survival among the subgroups belonging to this disease stage. Methods: Between January 2010 and December 2018, a total of 144 patients (125 males, 19 females; median age 60 years; range, 41 to 80 years) who were operated for non-small cell lung cancer in our clinic and whose pathological stage was reported as IIIA were retrospectively analyzed. Data including demographic and clinical characteristics of the patients, histopathological diagnosis, the standardized uptake value of the mass on positron emission tomography-computed tomography, tumor diameter, type of surgery, lymph node metastasis status, visceral pleural invasion, and overall and disease-free survival rates were recorded. Results: The median survival was 39 (range, 27.8 to 46.1) months and the five-year overall survival rate was 28%. The mean tumor diameter was 4.3±2.7 cm. The median disease-free survival was 37 (range, 28.1 to 48.6) months and the five-year disease-free survival rate was 26.9%. In the multivariate analysis, overall survival and disease-free survival in T2N2M0 subgroup were significantly worse than the other subgroups. The other poor prognostic factors of survival were the standardized uptake value of the tumor, pneumonectomy, and histopathological subtypes other than squamous cell carcinoma and adenocarcinoma. Parietal pleural invasion was significantly associated with worse disease-free survival rates. Conclusion: Our results showed that there may be significant survival differences between subgroups created by tumor histopathology, lymph node invasion and the type of surgery in a heterogeneous lung cancer stage.

Objectives. To investigate the prognostic factors and treatment outcomes of primary parotid carcinoma treated with surgery and postoperative radiotherapy (PORT).Methods. We reviewed retrospectively 57 patients with primary parotid carcinoma who were treated with surgery and PORT between 2005 and 2014. Superficial parotidectomy was performed in 19 patients, total parotidectomy in 10 patients, and total parotidectomy with lymph node dissection in 28 patients PORT on the tumor bed was performed in 41 patients, while PORT on tumor bed and ipsilateral cervical lymph nodes was performed in 16 patients.Results. With a median follow-up of 66 months, the 5-year overall survival, disease-free survival, locoregional control, and distant control rates were 77.0%, 60.2%, 77.6%, and 72.8%, respectively. The 5-year overall survival by stage was 100%, 100%, 80.0%, and 46.4% in stage I, II, III, and IV, respectively. Recurrences at primary lesions were found in seven patients, while at cervical nodes in six patients. Distant recurrences were developed in 12 patients. No patient with the low and intermediate histologic grade developed distant failure. As prognostic factors, the histologic grade for overall survival (P=0.005), pathological T-stage (P=0.009) and differentiation grade (P=0.009) for disease-free survival, pathological T-stage for locoregional control (P=0.007), and lympho-vascular invasion (P=0.023) for distant recurrence were significant on multivariate analysis.Conclusion. This study revealed that differentiation grade, histologic grade, pathological T-stage, and lympho-vascular invasion were significant independent prognostic factors on clinical outcomes.

Purpose The Intergroup 00-99 Trial for nasopharyngeal cancer (NPC) showed a benefit of adding chemotherapy to radiotherapy. However, there were controversies regarding the applicability of the results to patients in endemic regions. This study aims to confirm the findings of the 00-99 Trial and its applicability to patients with endemic NPC. Patients and Methods Between September 1997 and May 2003, 221 patients were randomly assigned to receive radiotherapy (RT) alone (n = 110) or chemoradiotherapy (CRT; n = 111). Patients in both arms received 70 Gy in 7 weeks using standard RT portals and techniques. Patients on CRT received concurrent cisplatin (25 mg/m2 on days 1 to 4) on weeks 1, 4, and 7 of RT and adjuvant cisplatin (20 mg/m2 on days 1 to 4) and fluorouracil (1,000 mg/m2 on days 1 to 4) every 4 weeks (weeks 11, 15, and 19) for three cycles after completion of RT. All patients were analyzed by intent-to-treat analysis. The median follow-up time was 3.2 years. Results Distant metastasis occurred in 38 patients on RT alone and 18 patients on CRT. The difference in 2-year cumulative incidence was 17% (95% CI, 14% to 20%; P = .0029). The hazard ratio (HR) for disease-free survival was 0.57 (95% CI, 0.38 to 0.87; P = .0093). The 2- and 3-year overall survival (OS) rates were 78% and 85% and 65% and 80% for RT alone and CRT, respectively. The HR for OS was 0.51 (95% CI, 0.31 to 0.81; P = .0061). Conclusion This report confirms the findings of the Intergroup 00-99 Trial and demonstrates its applicability to endemic NPC. This study also confirms that chemotherapy improves the distant metastasis control rate in NPC.

We have previously reported the results of a randomized trial that demonstrated the survival benefit of adjuvant chemotherapy in the treatment of patients with high-grade extremity sarcomas compared with no chemotherapy. This regimen included doxorubicin, cyclophosphamide, and methotrexate. This report updates and extends our experience. The median follow-up of this trial is now 7.1 years and reveals a 5-year disease-free survival of 75% and 54% for chemotherapy and no chemotherapy groups, respectively (two-sided P [P2] = .037). The 5-year overall survival for patients in this trial was 83% and 60% for the chemotherapy and no chemotherapy groups, respectively, with a trend towards improved survival in the chemotherapy arm (P2 = .124). Because of doxorubicin-induced cardiomyopathy we performed a subsequent randomized trial comparing this high-dose regimen to reduced cumulative doses of doxorubicin and cyclophosphamide without methotrexate. Eighty-eight patients were entered into this trial which has a median follow-up of 4.4 years. The 5-year disease-free and overall survival for patients treated with the reduced doses of chemotherapy was 72% and 75%, respectively, and was not significantly different from the high-dose regimen. No patients developed congestive heart failure on this study. We conclude that adjuvant chemotherapy improves disease-free survival in patients with extremity soft-tissue sarcomas. The overall survival advantage in patients receiving adjuvant chemotherapy in our initial randomized high-dose chemotherapy trial has diminished though it continues to favor the chemotherapy group. A reduced-dose chemotherapy regimen was found to be comparable to the high-dose regimen.
