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.

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.

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.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

Purpose To report mature results of a randomized trial that compared extended-field radiotherapy (EFRT) versus pelvic radiotherapy with concomitant fluorouracil and cisplatin (CTRT) in women with locoregionally advanced carcinomas of the uterine cervix. Patients and Methods Four hundred three women with cervical cancer were randomly assigned to receive either EFRT or CTRT. Patients were eligible if they had stage IIB to IVA disease, stage IB to IIA disease with a tumor diameter ≥ 5 cm, or positive pelvic lymph nodes. Patients were stratified by stage and by method of lymph node evaluation. Results The median follow-up time for 228 surviving patients was 6.6 years. The overall survival rate for patients treated with CTRT was significantly greater than that for patients treated with EFRT (67% v 41% at 8 years; P < .0001). There was an overall reduction in the risk of disease recurrence of 51% (95% CI, 36% to 66%) for patients who received CTRT. Patients with stage IB to IIB disease who received CTRT had better overall and disease-free survival than those treated with EFRT (P < .0001); 116 patients with stage III to IVA disease had better disease-free survival (P = .05) and a trend toward better overall survival (P = .07) if they were randomly assigned to CTRT. The rate of serious late complications of treatment was similar for the two treatment arms. Conclusion Mature analysis confirms that the addition of fluorouracil and cisplatin to radiotherapy significantly improved the survival rate of women with locally advanced cervical cancer without increasing the rate of late treatment-related side effects.

144 Background: The aim of this study is to evaluate the long-term clinical and oncologic outcome of ESD for differentiated EGC of an expanded indication compared to surgical resection. Methods: Retrospective analyses were performed in patients who underwent ESD or surgical resection for EGC of an expanded indication from 2006 and 2008 in Incheon St. Mary’s Hospital, Seoul St. Mary’s Hospital, Yeouido St. Mary’s Hospital, and St. Paul’s Hospital. First arm study was performed according to pre-ESD diagnosis including pathologic diagnosis and endoscopic findings. Second arm study was obtained from post-ESD final pathologic result. All the patients were checked with endoscopy and stomach CT regularly at least 5 years. Clinical outcomes, disease free survival and overall survival were compared between the ESD group and surgical resection group in each arm. Results: In first arm study, 41 patients who received ESD and 106 patients who received surgical resection were enrolled. Metachronous recur was found in 4 patients among ESD group and in 2 patients among surgical resection group during the follow up period. There was no local recurrence in both groups. The disease free survival was not different between the two groups (ESD vs surgical resection; 87.8 vs 95.3%, p=0.291). The 5-year overall survival rate was 100% in both groups. In second arm study, 74 patients who received ESD and 165 patients who received surgical resection were enrolled. Metachronous recur was found in 5 patients among ESD group and in 2 patients among surgical resection group during the follow up period. Local recurrence did not occur in both groups. Surgical resection group was superior to ESD group in disease free survival (97.6% vs 87.6%, p=0.002). The 5-year overall survival rate was 100% in both groups. Conclusions: ESD for EGC might be acceptable considering the overall survival rates. However, intensive surveillance should be performed to find the metachronous recur after ESD.

e15167 Background: Neoadjuvant chemoradiation has become the standard approach for treatment of locally advanced rectal cancers. Magnetic Resonence Imaging (MRI) is the staging modality of choice in rectal carcinoma. Recent reports have studied the impact of MRI on local recurrence and survival both in treatment naïve and post treatment settings Methods: A retrospective analysis of prospective database was performed over a period of 1 year. All pretreatment patients with carcinoma of rectum were included in the study. The status of CRM on MRI was compared to that on the histopathology and as a predictor of recurrence and survival. For analysis, the MRI scans done for patients at presentation were labeled as MRIT. This included all patients irrespective of further treatment received. Patients who were treated with NACTRT had two MRI scans. The MRI at presentation in this subset of patients was labeled as MRI1 and the reassessment MRI after NACTRT was labeled as MRI2. Thus, MRI1 represented a subset of MRIT with locally advanced tumors treated with NACTRT. All the sets of MRI scans were analyzed separately for prediction of CRM involvement and for their effect on local recurrence and survival rates. Results: 221 patients were included with a median follow-up 30 months. Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of MRIT, MRI1 and MRI2 to predict CRM status were 50%, 62.3%, 96.5%, 5.6% and 61.8%, 50%, 55%, 95%, 6% and 54.7% and 77.8%, 63.7%, 98%, 11%, 64.5% respectively. On multivariate analysis pathological positive margins alone predicted a poor overall survival (OS) whereas involved CRM on pathology and pretreatment MRI predicted poorer disease free survival and OS Conclusions: CRM status on pathology remains the most important prognostic factor to impact overall survival, disease free survival and local recurrence. CRM status on MRI at presentation alone has significant impact on disease free survival and local recurrence. Although MRI done after neoadjuvant treatment may not predict survival, it has a role in helping modify the surgical approach with a goal to achieve a negative CRM on pathology.

Purpose We update Radiation Therapy Oncology Group trial 8911 (USA Intergroup 113), a comparison of chemotherapy plus surgery versus surgery alone for patients with localized esophageal cancer. The relationship between resection type and between tumor response and outcome were also analyzed. Patients and Methods The chemotherapy group received preoperative cisplatin plus fluorouracil. Outcome based on the type of resection (R0, R1, R2, or no resection) was evaluated. The main end point was overall survival. Disease-free survival, relapse pattern, the influence of postoperative treatment, and the relationship between response to preoperative chemotherapy and outcome were also evaluated. Results Two hundred sixteen patients received preoperative chemotherapy, 227 underwent immediate surgery. Fifty-nine percent of surgery only and 63% of chemotherapy plus surgery patients underwent R0 resections (P = .5137). Patients undergoing less than an R0 resection had an ominous prognosis; 32% of patients with R0 resections were alive and free of disease at 5 years, only 5% of patients undergoing an R1 resection survived for longer than 5 years. The median survival rates for patients with R1, R2, or no resections were not significantly different. While, as initially reported, there was no difference in overall survival for patients receiving perioperative chemotherapy compared with the surgery only group, patients with objective tumor regression after preoperative chemotherapy had improved survival. Conclusion For patients with localized esophageal cancer, whether or not preoperative chemotherapy is administered, only an R0 resection results in substantial long-term survival. Even microscopically positive margins are an ominous prognostic factor. After a R1 resection, postoperative chemoradiotherapy therapy offers the possibility of long-term disease-free survival to a small percentage of patients.

ABSTRACT Background: Laparoscopic hepatectomy has presented great importance for treating malignant hepatic lesions. Aim: To evaluate its impact in relation to overall survival or disease free of the patients operated due different hepatic malignant tumors. Methods: Thirty-four laparoscopic hepatectomies were performed in 31 patients with malignant neoplasm. Patients were distributed as: Group 1 - colorectal metastases (n=14); Group 2 - hepatocellular carcinoma (n=8); and Group 3 - non-colorectal metastases and intrahepatic cholangiocarcinoma (n=9). The conversion rate, morbidity, mortality and tumor recurrence were also evaluated. Results: Conversion to open surgery was 6%; morbidity 22%; postoperative mortality 3%. There was tumor recurrence in 11 cases. Medians of overall survival and disease free survival were respectively 60 and 46 m; however, there was no difference among studied groups (p>0,05). Conclusion: Long-term outcomes of laparoscopic hepatectomy for treating hepatic malignant tumors are satisfactory. There is no statistical difference in relation of both overall and disease free survival among different groups of hepatic neoplasms.

This study evaluated the correlation between tumor-associated macrophages (TAMs) and long-term oncologic outcomes in colorectal cancer (CRC). We evaluated TAMs based on the expression of CD68, CD11c, and CD163 as optimal markers via immunohistochemistry in 148 patients with CRC who underwent surgical resection between September 1999 and August 2004. A high proportion of CD68-positive macrophages were associated with the occurrence of distant metastasis. A low proportion of CD11c-positive macrophages were associated with unfavorable overall survival (OS) and disease-free survival. CD11c-positive macrophages were found to act as independent prognostic factors for OS. An analysis of our long-term data indicated that TAMs are significantly associated with OS and prognosis in CRC.
