Weekly Cisplatin

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.

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.

PURPOSE To evaluate the clinical outcomes in patients with cervical cancer with limited residual disease at brachytherapy (BT) treated with point-based dose prescription. METHODS Patients with locally advanced squamous cell carcinoma of the cervix treated with computed tomography (CT)-based intracavitary BT were considered for analysis. Patients with good response to external beam radiotherapy and limited residual disease suitable for intracavitary BT alone were included. Postapplication CT scans were performed before each fraction and individual plans were made for each session. The dose per fraction was 9Gy high dose rate, prescribed to point-A. Two sessions were planned, 1 week apart. The organs at risk were contoured, and cumulative dose-volume histograms were computed. Local control, pelvic control, disease-free survival, and overall survival were evaluated and late toxicities were documented. RESULTS Four hundred ninety patients were included. Overall, 79.8% had International Federation of Gynecology and Obstetrics (FIGO) stage IB2 to IIB disease and 20.2% had stage III to IVA disease. Median dose at point A (EQD210Gy) was 74.4 Gy (interquartile range [IQR] 72.3-74.5 Gy) and median D2cc (EQD23Gy) for bladder, rectum, and sigmoid were 82.5 Gy (IQR, 65.5-90.8 Gy), 66.5 Gy (IQR, 60.7-75.7 Gy), and 54.1 Gy (IQR, 50.5-77.3 Gy), respectively. At a median follow-up of 62 (IQR, 33-87) months, the 5-year local and pelvic control rates were 90.1% and 88.3%, respectively. The 5-year disease-free survival was 80% and overall survival was 88%. Rates of grade 3-4 bladder and rectosigmoid toxicities were 6.93% and 4.08%, respectively. CONCLUSION In patients with limited residual disease at BT, point-based dose prescription with CT planning results in good local control and acceptable toxicity. In a resource-constrained setting, patients may be triaged to receive point-based BT or magnetic resonance imaging–guided adaptive BT depending on the extent of residual disease.

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.

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.

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.

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: To determine outcomes in local-regional control, disease-free survival, and overall survival in patients with locally advanced breast cancer (LABC) who present with ipsilateral supraclavicular metastases and who are treated with combined-modality therapy.PATIENTS AND METHODS: Seventy patients with regional stage IV LABC, which is defined by our institution as LABC with ipsilateral supraclavicular adenopathy without evidence of distant disease, received treatment on three prospective trials of neoadjuvant chemotherapy. All patients received neoadjuvant chemotherapy with cyclophosphamide, doxorubicin, and fluorouracil, or cyclophosphamide, doxorubicin, vincristine, and prednisone. Patients then received local therapy that consisted of either total mastectomy and axillary lymph node dissection (ALND) or segmental mastectomy and ALND before or after irradiation. Patients with no response to neoadjuvant chemotherapy were treated with surgery and/or radiotherapy. After completion of local therapy, chemotherapy was continued for four to 15 cycles, followed by radiotherapy. Patients older than 50 years who had estrogen receptor–positive tumors received tamoxifen for 5 years.RESULTS: Median follow-up was 11.6 years (range, 4.8 to 22.6 years). Disease-free survival rates at 5 and 10 years were 34% and 32%, respectively. The median disease-free survival was 1.9 years. Overall survival rates at 5 and 10 years were 41% and 31%, respectively. The median overall survival was 3.5 years. The overall response rate (partial and complete responses) to induction chemotherapy was 89%. No treatment-related deaths occurred.CONCLUSION: Patients with ipsilateral supraclavicular metastases but no other evidence of distant metastases warrant therapy administered with curative intent, ie, combined-modality therapy consisting of chemotherapy, surgery, and radiotherapy. Patients with ipsilateral supraclavicular metastases should be included in the stage IIIB category of the tumor-node-metastasis classification because their clinical course and prognosis are similar to those of patients with stage IIIB LABC.

7708 Background: Examine the results of tri-modality therapy for malignant pleural mesothelioma (MPM). Methods: Protocol consisted of induction cisplatin-based chemotherapy, followed by extrapleural pneumonectomy (EPP) and adjuvant hemithoracic radiation therapy (RT) to 54 Gy. Results: A total of 60 patients were suitable candidates for tri-modality therapy between 01/2001 and 01/2007. Induction chemotherapy was administered to 56 patients; 4 patients underwent EPP without induction chemotherapy because of patient refusal (n=2), previous chemotherapy (n=1) and sarcomatoid MPM (n=1). Chemotherapy included vinorelbine/cisplatin (n=26), pemetrexed/cisplatin (n=26) and gemcitabine/cisplatin (n=4). EPP was performed in 47 patients; 13 patients did not undergo EPP because of tumor progression during chemotherapy (n=2), extensive chest wall involvement at surgery (n=6), or involvement of mediastinal lymph nodes at mediastinoscopy (n=5). Three patients (6%) died within 30 days of surgery. Pathological stage was II (n=6), III (n=35), and IV (n=6). Adjuvant RT was administered postoperatively to 36 patients and is ongoing in 5 patients; 6 patients did not receive adjuvant RT because of fatigue (n=5) or previous RT (n=1), and 4 patients did not complete RT up to 54 Gy. Overall survival for the 23 patients who completed the tri-modality therapy was 37% at 3 years with a median survival of 15 months. Eleven of the 23 patients had recurrence after a median of 8 months (range, 2–13 months). Recurrences were locoregional (n=2), in contralateral chest (n=3), abdomen (n=3), contralateral chest and abdomen (n=2), or pericardium (n=1). Among patients undergoing EPP, disease-free survival was longer in patients undergoing adjuvant high dose hemithoracic RT (p=0.07), in epithelial tumors (p=0.03), and in early stage (p=0.07). Overall survival was influenced by histology (p=0.007) and stage (p=0.05), but not by adjuvant high dose hemithoracic RT (p=0.5). The type of chemotherapy had no impact on disease-free and overall survival. Conclusions: Aggressive tri-modality therapy is feasible in selected patient with MPM. Adjuvant high dose hemithoracic RT can improve disease free survival and achieve good local control. No significant financial relationships to disclose.

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.
