Objective: To explore the safety and efficacy of oxaliplatin plus capecitabine (CapeOX) or oxaliplatin plus S-1 (SOX) regimen neoadjuvant chemotherapy in the treatment of advanced gastric cancer. Methods: A retrospective cohort study was performed. Clinical data of patients diagnosed as advanced gastric cancer undergoing CapeOX/SOX neoadjuvant chemotherapy and standard laparoscopic radical operation for gastric cancer in Ruijin Hospital of Shanghai Jiaotong University School of Medicine from April 2016 to April 2019 were retrospectively collected. Inclusion criteria were as follows: (1) age≥18 years; (2) gastric adenocarcinoma was confirmed by histopathology and the clinical stage was T3-4aN+M0; (3) tumor could be resectable; (4) preoperative neoadjuvant chemotherapy was CapeOX or SOX regimen without radiotherapy or other regimen chemotherapy; (5) no other concurrent malignant tumor; (6) the Eastern Cooperative Oncology Group (ECOG) score ≤ 1; (7) no bone marrow suppression; (8) normal liver and kidney function. Exclusion criteria were as follows: (1) patients with recurrent gastric cancer; (2) patients receiving emergency surgery due to tumor perforation, bleeding, obstruction, etc.; (3) allergy to oxaliplatin, S-1, capecitabine or any drug excipients; (4) diagnosed with coronary heart disease, cardiomyopathy, or the New York Heart Association class III or IV; (5) pregnant or lactating women. A total of 118 patients were enrolled as the neoadjuvant chemotherapy group, and 379 patients with locally advanced gastric cancer who received surgery combined with postoperative adjuvant chemotherapy over the same period simultaneously were included as the adjuvant chemotherapy group. After propensity score matching was performed including gender, age, ECOG score, tumor site, clinical stage, chemotherapy regimen and other factors by 1:1 ratio, there were 40 cases in each group. The differences between the two groups in general conditions, efficacy of neoadjuvant chemotherapy, intraoperative conditions, postoperative conditions, histopathological results, chemotherapy-related adverse events, and survival status were compared and analyzed. Results: Comparison of baseline demographics between the two groups showed no statistically significant difference (all P>0.05). In the neoadjuvant chemotherapy group, 5.0% (2/40) of patients achieved clinical complete response, 57.5% (23/40) achieved partial response, 32.5% (13/40) remained stable disease, and 5.0% (2/40) had disease progression before surgery. Objective response rate was 62.5% (25/40), and disease control rate was 95.0% (38/40). There were no statistically significant differences between neoadjuvant chemotherapy group and adjuvant chemotherapy group in terms of operation time, intraoperative blood loss, number of lymph node harvested, length of postoperative hospital stay, and postoperative mortality and morbidity (all P>0.05). Postoperative complications were well managed with conservative treatment. No Clavien-Dindo IV or V complications were observed in both groups. Pathological results showed that the proportion of patients with pathological stage T1 in the neoadjuvant chemotherapy group was significantly higher than that in the adjuvant chemotherapy group [27.5% (11/40) vs. 5.0% (2/40)], while the proportion of patients with pathological stage T3 was significantly lower than that in the adjuvant chemotherapy group [20.0% (8/40) vs. 45.0% (18/40)], with statistically significant difference (χ(2)=15.432, P=0.001). In the neoadjuvant chemotherapy group, there were 4 cases of tumor regression grade 0, 8 cases of grade 1, 16 cases of grade 2, and 12 cases of grade 3. The pathological complete response rate was 10% (4/40), the overall pathological response rate was 70.0% (28/40). There was no statistically significant difference in the incidence of chemotherapy-related adverse events between neoadjuvant chemotherapy group and adjuvant chemotherapy group [40% (16/40) vs. 37.5% (15/40), P>0.05). There were no statistically significant differences in OS (43 months vs. 40 months) and 3-year OS rate (66.1% vs. 59.8%) between neoadjuvant chemotherapy group and adjuvant chemotherapy group (P=0.428). The disease-free survival (DFS) and 3-year DFS rates of the neoadjuvant chemotherapy group were significantly superior to those of the adjuvant chemotherapy group (36 months vs. 28 months, 51.4% vs. 35.8%, P=0.048). Conclusion: CapeOX or SOX regimen neoadjuvant chemotherapy is a safe, effective and feasible treatment mode for advanced gastric cancer without increasing surgical risk and can improve the DFS of patients.

Objective: Radiotherapy is one of the standard treatments for pelvic malignant tumors. However, researches associated with intestinal radiation injury and the quality of life (QoL) of patients receiving radiotherapy were lacking in the past. This study aims to analyze the occurrence of radiation-induced rectal injury after adjuvant radiotherapy for pelvic malignant tumors and call for more attention on this issne. Methods: A retrospectively observational study was conducted. Case data of cervical cancer patients from the database of STARS phase 3 randomized clinical trial (NCT00806117) in Sun Yat-sen University Cancer Center were analyzed. A total of 848 cervical cancer patients who received adjuvant radiation following hysterectomy and pelvic lymphadenectomy in Sun Yat-sen University Cancer Center from February 2008 to August 2015 were recruited. The pelvic radiation dosage was 1.8 Gy/day or 2.0 Gy/day, five times every week, and the total dosage was 40-50 Gy. Among 848 patients, 563 patients received radiation six weeks after surgery, of whom 282 received adjuvant radiation alone and 281 received concurrent chemoradiotherapy (weekly cisplatin); other 285 patients received sequential chemoradiotherapy (paclitaxel and cisplatin). Acute adverse events, chronic radiation damage of rectum, and QoL were collected and analyed. The digestive tract symptoms and QoL were evaluated based on EORTC QLQ-C30 questionnaires at one week after surgery (M0), during adjuvant therapy period (M1), and at 12 months and 24 months after the completion of treatments (M12 and M24), respectively. Higher scores in the functional catalog and overall quality of life indicated better quality of life, while higher scores in the symptom catalog indicated severe symptoms and worse QoL. Chronic radiation rectal injury was defined as digestive symptoms that were not improved within three months after radiotherapy. Grading standard of acute adverse events and chronic radiation rectal injury was according to the gastrointestinal part of National Cancer Institute Common Terminology Criteria for Adverse Events, version 4.0 (NCI-CTCAE Version 4.0). Results: The mean total radiation dosage of 848 patients was (47.8±4.6) Gy. During adjuvant therapy, the common symptoms of acute intestinal dysfunction were nausea (46.0%, 390/848), vomiting (33.8%, 287/848), constipation (16.3%, 138/848) and abdominal pain (10.3%, 87/848). At M12 and M24, the number of 0 QLQ-C30 questionnaires collected was 346 and 250, respectively. QLQ-C30 questionnaires showed that the scores of nausea or vomiting, appetite decrease, diarrhea, constipation, etc. were improved obviously at M12 or M24 compared with those at M0 or during M1 (all P<0.05). As the extension of the follow-up time, the score of the overall QoL of patients gradually increased [M0: 59.7 (0.0-100.0); M1: 63.1 (0.0-100.0); M12: 75.2 (0.0-100.0); M24: 94.1 (20.0-120.0); H=253.800, P<0.001]. Twelve months after the completion of treatments, the incidence of chronic radiation rectal injury was 9.8% (34/346), mainly presenting as abdominal pain, constipation, stool blood, diarrhea, mostly at level 1 to 2 toxicity (33/34, 97.1%). One patient (0.3%) developed frequent diarrhea (>8 times/d), which was level 3 toxicity. Twenty-four months after all treatments, the incidence of chronic radiation rectal injury was 9.6% (24/250), which was not decreased significantly compared to that in the previous period (χ(2)=0.008, P=0.927). The symotoms of one patient with level 3 toxicity was not relieved. Conclusions: The common symptoms of patients with pelvic maligant tumors during postoperative adjuvant radiotherapy include nausea, vomiting, constipation, abdominal pain and diarrhea. These symptoms are alleviated obviously at 12 and 24 months after adjuvant radiotherapy, and the QoL is significantly improved. However, a few patients may develop chronic radiation rectal injury which is not improved for years or even decades, and deserves attention in clinical practice.

PURPOSE: The purpose of this study was to evaluate the risk of central nervous system (CNS) failure in Korean patients with human epidermal growth factor receptor 2 (HER2)-enriched breast cancer treated with surgery followed by postoperative radiotherapy (RT). METHODS: A total of 749 patients from eight institutions were enrolled in this study. All of them underwent surgery followed by postoperative RT from 2003 to 2011; 246 (32.8%) received neoadjuvant chemotherapy and 649 (81.7%) received adjuvant chemotherapy. Adjuvant trastuzumab was administered to 386 patients (48.6%). RESULTS: The median follow-up duration was 84 (range, 8–171) months. The 7-year disease-free and overall survival rates were 79.0% and 84.2%, respectively. On multivariate analysis, mastectomy, nodal involvement, and presence of lymphatic invasion were correlated with poor overall survival (p = 0.004, 0.022, and 0.011, respectively), whereas T stage and lymphatic invasion were associated with disease-free survival (p = 0.018 and 0.005, respectively). Regarding CNS failures, 30 brain metastases, 2 leptomeningeal metastases, and 8 brain and leptomeningeal metastases were noted. The 7-year CNS relapse-free survival rates in patients receiving and not receiving trastuzumab were 91.2% and 96.9%, respectively (p = 0.005). On multivariate analysis, the administration of adjuvant trastuzumab was the only prognostic factor in predicting a higher CNS failure rate (hazard ratio, 2.260; 95% confidence interval, 1.076–4.746; p = 0.031). CONCLUSION: Adjuvant trastuzumab was associated with higher CNS failure rate in Korean patients with HER2-enriched breast cancer. Close monitoring and reasonable approaches such as CNS penetrating HER2 blockades combined with the current standard therapy could contribute to improving intracranial tumor control and quality of life in patients with CNS metastasis from HER2-enriched breast cancer.

PURPOSE: The use of immediate breast reconstruction (IBR) has been debated because it may be a causative factor in adjuvant treatment delay and may subsequently increase the probability of recurrence. We investigated whether IBR was related to adjuvant treatment delay and survival outcomes. METHODS: We retrospectively analyzed the duration from operation to adjuvant treatment administration and survival outcomes according to IBR status among patients with breast cancer who underwent mastectomy followed by adjuvant chemotherapy from January 2005 to December 2014. Propensity score matching was performed to balance the clinicopathologic baseline characteristics between patients who did and did not undergo IBR. RESULTS: Of 646 patients, 107 (16.6%) underwent IBR, and the median follow-up was 72 months. The median duration from surgery to adjuvant chemotherapy was significantly longer in patients who underwent IBR than in those who did not (14 vs. 12 days, respectively, p = 0.008). Based on propensity score matching, patients who underwent IBR received adjuvant therapy 3 days later than those who did not (14 vs. 11 days, respectively, p = 0.044). The duration from surgery to post-mastectomy radiation therapy (PMRT) did not significantly differ between the 2 groups. Local recurrence-free survival, regional recurrence-free survival, systemic recurrence-free survival, and overall survival were also not significantly different between the 2 groups (p = 0.427, p = 0.445, p = 0.269, and p = 0.250, respectively). In the case-matched cohort, survival outcomes did not change. CONCLUSION: IBR was associated with a modest increase in the duration from surgery to chemotherapy that was statistically but not clinically significant. Moreover, IBR had no influence on PMRT delay or survival outcomes, suggesting that it is an acceptable option for patients with non-metastatic breast cancer undergoing mastectomy.

Eccrine porocarcinoma is a rare malignant tumor arising from the intraepidermal ductal portion of the eccrine sweat gland. It develops either spontaneously or from a long standing benign eccrine poroma. This entity usually affects older people and is commonly located on the lower extremities, the trunk, and the head. We report a case of eccrine porocarcinoma on the left cheek in an 85-year-old male. In our case, the tumor was treated with wide excision and postoperative adjuvant radiation therapy. The patient recovered well without local recurrence and distant metastasis during the 14-month follow-up period. Wide excision and postoperative adjuvant radiation therapy can be considered as a safe and effective treatment option in treating patients with eccrine porocarcinoma.

Supratentorial extraventricular anaplastic ependymoma (SEAE) in adults is a relatively rare intracranial tumor. Because of the very low prevalence, only a few cases have been reported. According to a recent study, SEAE is associated with a poor prognosis and there is no definite consensus on optimal treatment. We report a case of an adult SEAE patient who had no recurrence until seven years after a gross total resection (GTR) followed by conventional radiotherapy. A 42-year-old male had a persistent mild headache, left facial palsy, dysarthria, and left hemiparesis. Preoperative neuroimaging revealed an anaplastic astrocytoma or supratentorial ependymoma in the right frontal lobe. A GTR was performed, followed by adjuvant radiotherapy. Histologic and immunohistochemical results revealed anaplastic ependymoma. After seven years of initial therapy, a regular follow-up MRI showed a 3-cm-sized partially cystic mass in the same area as the initial tumor. The patient underwent a craniotomy, and a GTR was performed. Histopathologic examination revealed recurrence of the SEAE. External radiotherapy was performed. The patient has been stable without any disease progression or complications for 12 months since the surgery for recurrent SEAE.

OBJECTIVE: To compare the survival outcomes of adjuvant radiotherapy and chemotherapy in women with uterine-confined endometrial cancer with uterine papillary serous carcinoma (UPSC) or clear cell carcinoma (CCC). METHODS: Medical records of 80 women who underwent surgical staging for endometrial cancer were retrospectively reviewed. Stage I UPSC and CCC were pathologically confirmed after surgery. Survival outcomes were compared between the adjuvant radiotherapy and chemotherapy groups. RESULTS: Fifty-four (67.5%) and 26 (32.5%) women had UPSC and CCC, respectively. Adjuvant therapy was administered to 59/80 (73.8%) women (25 radiotherapy and 34 chemotherapy). High preoperative serum cancer antigen-125 level (25.1±20.2 vs. 11.5±6.5 IU/mL, p < 0.001), open surgery (71.2% vs. 28.6%, p=0.001), myometrial invasion (MI) ≥1/2 (33.9% vs. 0, p=0.002), and lymphovascular space invasion (LVSI; 28.8% vs. 4.8%, p=0.023) were frequent in women who received adjuvant therapy compared to those who did not. However, the histologic type, MI ≥1/2, and LVSI did not differ between women who received adjuvant radiotherapy and those who received chemotherapy. The 5-year progression-free survival (78.9% vs. 80.1%, p>0.999) and overall survival (77.5% vs. 87.8%, p=0.373) rates were similar between the groups. Neither radiotherapy (hazard ratio [HR]=1.810; 95% confidence interval [CI]=0.297–11.027; p=0.520) nor chemotherapy (HR=1.638; 95% CI=0.288–9.321; p=0.578) after surgery was independently associated with disease recurrence. CONCLUSION: Our findings showed similar survival outcomes for adjuvant radiotherapy and chemotherapy in stage I UPSC and CCC of the endometrium. Further large study with analysis stratified by MI or LVSI is required.

OBJECTIVE: The aim of this study was to determine the possible prognostic factors in patients with uterine leiomyosarcoma (LMS). METHODS: This study retrospectively investigated 50 patients with uterine LMS treated at the Samsung Medical Center between 2001 and 2017. To analyze the prognostic significance of factors for recurrence-free survival (RFS), overall survival (OS), and survival after recurrence, the log-rank test and Cox proportional hazards model were used for univariate and multivariate analysis. RESULTS: Of the 50 patients, 30 (60.0%) experienced recurrence and 16 (32.0%) died within a median follow-up period of 21 (range, 3–99) months. Multivariate analysis revealed that older age, absence of residual tumor after surgery, lower mitotic count, and a history of adjuvant radiotherapy at first treatment were significantly associated with better RFS. Presence of residual tumor after surgery and severe nuclear atypia were associated with poor OS. In the analysis of survival after recurrence, hematogenous recurrence, severe nuclear atypia, and presence of residual tumor at primary surgery were significantly associated with worse prognosis. Notably, residual tumor status at primary surgery was associated with RFS, OS, and survival after recurrence. CONCLUSION: We demonstrated the possible prognostic factors for RFS, OS, and survival after recurrence for patients with LMS. These results may provide useful information for patients with LMS.

Annals of Surgical Treatment and Research 2019;97(5):239-244
PURPOSE: An enhanced recovery after surgery (ERAS) protocol incorporates up-to-date perioperative care principles; the primary aim in using an ERAS protocol is to reduce issues that delay the recovery and cause the complications. The aim of this study was to compare outcomes associated with head and neck cancer surgery with free-flap reconstruction before and after implementation of an ERAS protocol. METHODS: Outcomes were analyzed by dividing patients into 2 groups: 29 patients in the non-ERAS group and 60 patients in the ERAS group. The ERAS group performed a prospective observational cohort study of patients who underwent a head and neck cancer surgery with free-flap reconstruction in Ajou University Hospital from August 2015 to December 2017. The non-ERAS group retrospectively reviewed the medical records of patients who had undergone the same surgery from August 2012 to July 2015. RESULTS: Demographics, comorbidities, hospital length of stay (LOS), postoperative complications, starting time of rehabilitation, and postoperative periods before radiotherapy for the non-ERAS and ERAS groups were compared. Hospital LOS was significantly lower for patients whose care followed the ERAS protocol than for patients in the non-ERAS group (30.87 ± 20.72 days vs. 59.66 ± 40.43 days, P < 0.0001). CONCLUSION: In this study, hospital LOS was reduced through fast recovery after the implementation of the ERAS protocol. Therefore, the ERAS protocol appeared feasible and safe in head and neck cancer surgery with free-flap reconstruction.

BACKGROUND: In immediate breast reconstruction using an extended latissimus dorsi musculocutaneous (eLDMC) flap, the volume of the flap decreases, which causes a secondary deformity of the breast shape. Since little research has investigated this decrease in muscle volume, the authors conducted an objective study to characterize the decrease in muscle volume after breast reconstruction using an eLDMC flap. METHODS: Research was conducted from October 2011 to November 2016. The subjects included 23 patients who underwent mastectomy due to breast cancer, received immediate reconstruction using an eLDMC flap without any adjuvant chemotherapy or radiotherapy, and received a computed tomography (CT) scan from days 7 to 10 after surgery and 6 to 8 months postoperatively. In 10 patients, an additional CT scan was conducted 18 months postoperatively. Axial CT scans were utilized to measure the volumetric change of the latissimus dorsi muscle during the follow-up period. RESULTS: In the 23 patients, an average decrease of 54.5% was observed in the latissimus dorsi muscle volume between the images obtained immediately postoperatively and the scans obtained 6 to 8 months after surgery. Ten patients showed an average additional decrease of 11.9% from 6–8 months to 18 months after surgery. CONCLUSIONS: We studied changes in the volume of the latissimus dorsi muscle after surgery using an eLDMC flap performed after a mastectomy without adjuvant chemotherapy or radiotherapy. In this study, we found that immediate breast reconstruction using a latissimus dorsi muscle flap led to a decrease in muscle volume of up to 50%.
