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.

radiotherapy or surgery who received apatinib between June 2016 and June 2017 were involved in this study. These patients experienced progression after first-line or second-line chemotherapy. There were 38 patients with cervical squamous cell carcinoma, 8 with adenocarcinoma, and 2 with adenosquamous carcinoma. Progression-free survival (PFS), overall survival (OS), and treatment-related adverse events (AEs) were reviewed and evaluated.RESULTS: All patients had complete follow-up records, and the median follow-up time was 14.5 months (5.5–20.5 months). Among the 48 patients, 14.58% achieved a partial response and 52.08% achieved stable disease. The overall response rate and disease control rate were 14.58% and 66.67%, respectively. The median time that the 48 patients received oral apatinib was 8.2 months. The median PFS was 4.6 months (95% confidence interval [CI]=3.31–5.26) and OS was 13.9 months (95% CI=8.37–17.96). The main apatinib-related adverse reactions were leukopenia (37.5%), neutropenia (41.67%), hemorrhage (37.5%), hypertension (33.33%), proteinuria (12.5%), fatigue (37.5%), and hand-foot syndrome (27.08%). Most of them were grade 1–2, and no drug-related death occurred.CONCLUSIONS: Apatinib can improve the disease control rate of recurrent and metastatic cervical cancer when chemotherapy has failed, and the treatment is well tolerated. This represents that apatinib may be a new treatment option for metastatic cervical cancer patients.]]>

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.

Serine protease inhibitor Kazal-type 1 (SPINK1) is a gene expressed from pancreatic acinar cell which its mutation is known to be associated with chronic pancreatitis (CP) and pancreatic cancer. We report a case of a 47-years-old female with nausea and weight loss with yellow discoloration of skin. Initial imaging and endoscopic study led us to an impression of chronic pancreatitis with pancreatic cancer with common bile-duct dilation. Biopsy result was confirmed with pancreatic adenocarcinoma and additional imaging revealed lymph node and bone metastasis. Our genetic analysis revealed 194+2T>C mutation of SPINK1. Biliary obstruction was successfully decompressed by stent insertion and underwent chemotherapy and radiotherapy. Although there is accumulating evidence of association between SPINK1 mutation and CP, the relationship between SPINK1 mutation and pancreatic cancer in CP patient is an emerging concept. Genetic analysis should be considered in patients with young age especially when diagnosed with both CP and pancreatic cancer.

OBJECTIVE: To explore the efficacy of radiotherapy combined with surgery for locally advanced rectal mucinous adenocarcinoma. METHODS: Clinical data of patients with locally advanced rectal mucinous adenocarcinoma (T3-4 and/or N+) diagnosed by postoperative pathology from 1992 to 2013 were retrieved from the US Surveillance, Epidemiology, and End Results (SEER) database. Patients with local excision only, tumor biopsy or combined organ excision and incomplete follow-up information were excluded. All the enrolled patients were divided into three groups according to different treatments, including surgery alone (SA) group, preoperative radiotherapy combined with surgery (RT+S) group and surgery combined with postoperative radiotherapy (S+RT) group. The extracted data included basic data of patients and tumor, treatment status, and follow-up results. The χ² test was used to compare the count data. Kaplan-Meier method was used to draw the survival curve and calculate the survival rate. The survival was analyzed and compared by Log-rank test. The R language 2.8.1 was used to match the patients as 1:1 pairing through the propensity score matching (PSM). The matching variables included gender, age at diagnosis, year at diagnosis, ethnicity, degree of tissue differentiation, TNM stage, depth of invasion, making the baseline data of subgroups comparable. The Cox proportional hazard model was used for multivariate analysis of prognostic factors. RESULTS: A total of 2 149 patients with locally advanced rectal mucinous adenocarcinoma were enrolled in the study, including 1 255 males (58.4%) and 894 females (41.6%). There were 706 patients (32.9%) in the SA group, 772 patients (35.9%) in the RT+S group and 671 patients (31.2%) in the S+RT group. In SA, RT+S and S+RT groups, the median overall survival time was 39, 85, and 74 months respectively; the 5-year overall survival (OS) rate was 38.7%, 56.5%, and 55.2% respectively; the median cancer-specific survival (CSS) time was 86, 127, and 111 months respectively, and the 5-year CSS rate was 53.7%, 62.2% and 60.7% respectively. In comparison among the 3 groups, the 5-year OS rate and CSS rate in the SA group were significantly lower than those in the RT+S group and S+RT group (all P<0.001); the 5-year OS rate and CSS rate between RT+S group and S+RT group were not significantly different (P=0.166 and 0.392,respectively). After the baseline data of subgroups were corrected through PSM, the 5-year OS rate and CSS rate in the SA group (n=375) were significantly lower than those in the RT+S group (n=375)(OS:40.1% vs. 54.5%, P<0.001; CSS:54.3% vs. 63.3%, P=0.023). The 5-year OS rate and CSS rate in the SA group (n=403) were also lower than those in the S+RT group (n=403) (OS:37.4% vs. 54.7%,P<0.001;CSS:51.6% vs. 61.0%,P=0.031). The 5-year OS rate and CSS rate between RT+S group (n=363) and S+RT group (n=363) were not significantly different (OS:51.7% vs. 55.5%, P=0.789; CSS:57.7% vs. 60.5%, P=0.484). Cox multivariate analysis showed that radiotherapy (HR=0.845, 95%CI: 0.790 to 0.903, P=0.001) was an independent prognostic factor for OS of locally advanced rectal mucinous adenocarcinoma; radiotherapy (HR=0.907, 95% CI: 0.835 to 0.985, P=0.021) was also an independent prognostic factor affecting CSS in patients with locally advanced rectal mucinous adenocarcinoma. CONCLUSION As compared with surgery alone, surgery combined with preoperative or postoperative radiotherapy is beneficial to the long-term survival of patients with locally advanced rectal mucinous adenocarcinoma.

BACKGROUND: Advanced epidermal growth factor receptor (EGFR)-mutant lung adenocarcinoma had a high overall incidence of brain metastasis during the full course, and local brain radiotherapy combined with systemic targeted therapy may be a better strategy. This study aimed to identify the prognostic factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients who received EGFR-tyrosine kinase inhibitors (EGFR-TKIs) in combination with gamma knife radiosurgery. METHODS: Retrospective analysis of EGFR-mutant lung adenocarcinoma patients with brain metastases which developed at initial diagnosis or during EGFR-TKIs treatment period were performed. Intracranial progression free survival (PFS) was statistically analyzed between different subgroups to find out the prognostic factors including gender, age, smoking history, extracranial metastasis, EGFR mutation type, size and number of intracranial lesions, carcino-embryonic antigen (CEA) level, lung-molGPA score and so on. RESULTS: A total of 74 EGFR-mutant brain-metastatic lung adenocarcinoma patients were enrolled in this study, with median intracranial PFS of 14.7 months. One-year intracranial-progression-free rate was 58.5%, and two-year rate was 22.2%. Univariate survival analysis showed that patients with lower CEA level at initial diagnosis (<10 ng/L)(16.9 months vs 12.6 months, P=0.012) and smaller intracranial lesions (<2 cm)(15.4 months vs 10.8 months, P=0.021) and higher lung-molGPA score (>3)(15 months vs 12.6 months, P=0.041) were prone to have a superior intracranial PFS. Multivariate analysis showed that CEA≥10 ng/mL and intracranial lesion≥2 cm were the independent risk factors of intracranial PFS. CONCLUSIONS EGFR-TKIs in combination with gamma knife radiosurgery was an efficient treatment option to control the cranial tumor lesion. CEA≥10 μg/L at initial diagnosis and intracranial lesion≥2 cm were the risk factors of EGFR-mutant brain-metastatic lung adenocarcinoma patients receiving EGFR-TKIs in combination with gamma knife radiosurgery.

PURPOSE: Tailgut cysts are rare congenital or developmental lesions that arise from vestiges of the embryological hindgut. They are usually present in the presacral space. We report our single-center experience with managing tailgut cysts. METHODS: We conducted a retrospective analysis of 24 patients with tailgut cyst treated surgically at the Colorectal Surgery Department of Severance Hospital, Yonsei University, Seoul, South Korea, between 2007–2018. RESULTS: This study included 24 patients (18 females) with a median age of 51.5 years (range, 21–68 years). Ten cases were symptomatic and 14 were asymptomatic. Cysts were retrorectal in 21 patients. Cysts were below the coccyx level in 16 patients, opposite the coccyx in 6, and above the coccyx in 2. Cysts were supralevator in 5 patients, had a supra- and infralevator extension in 18 patients, and were infralevator in 1. Ten patients were managed using an anterior laparoscopic approach, 11 using a posterior approach, and 3 using a combined approach. Mean cyst size was 5.5 ± 2.7 cm. Postoperative complications were Clavien-Dindo (CD) classification grade II in 9 patients (37.5%) and CD grade III in 1 (4.2%). The posterior approach group showed the highest rate of complications (P = 0.021). Patients managed using a combined approach showed a larger cyst size (P < 0.001), longer operation times (P < 0.001), and a greater likelihood of tumor level above the coccyx (P = 0.002) compared to other approaches. The tumors of 2 male patients were malignant: 1 was a neuroendocrine tumor treated with radiotherapy, while the other was a closely followed adenocarcinoma. Median follow-up was 12 months (range, 1–66 months) with no recurrence. CONCLUSION: Tailgut cysts are uncommon but can cause perineal or pelvic pain. Complete surgical excision via an appropriate approach according to tumor size, location, and correlation with adjacent pelvic floor muscles is the key treatment.

OBJECTIVES: This study evaluated the predictive factors for survival of patients with oral squamous cell carcinoma (OSCC) and investigated the overall and disease-specific survival (DSS) outcomes. MATERIALS AND METHODS: A total of 67 consecutive patients who underwent surgery for OSCC from January 2006 to November 2014 were included in this study. Patients were classified according to age, sex, pTNM stages, primary sites, smoking and alcohol drinking habits, depth of invasion, perineural and lymphovascular invasion, cell differentiation and postoperative radiotherapy. Kaplan-Meier methods were used to estimate the survival categorized by patient groups. Cox regression methods were used to investigate the main independent predictors of survival. RESULTS: Nineteen patients died of OSCC during follow-up periods. Another five patients died of other diseases including lung adenocarcinoma (n=1), cerebral infarction (n=1), general weakness (n=2), and pneumonia (n=1). The tongue (n=16) was the most common site for primary origin, followed by buccal mucosa (n=15), mandibular gingiva (n=15), maxillary gingiva (n=9), floor of mouth (n=9), retromolar trigone (n=2), and palate (n=1). Eleven patients had pTNM stage I disease, followed by stage II (n=22) and stage IV (n=34). No patients had pTNM stage III disease in this study. The overall survival of all patients was 64.2% and the DSS was 71.6%. DSS of patients with stage I and II disease was 100%. Stepwise Cox regression showed the two predictors for DSS were pTNM stage (P<0.0001, odds ratio=19.633) and presence of metastatic lymph nodes (P=0.0004, odds ratio=0.1039). CONCLUSION: OSCC has been associated with poor prognosis; however, there were improved survival outcomes compared with past studies. Advanced-stage disease and presence of metastatic lymph nodes were associated with poorer survival compared with early-stage OSCC and absence of neck node metastasis. Stage I and II OSCC were associated with excellent survival results in this study.

We report a rare case of long-term survival in a patient who received local therapy and salvage chemotherapy for recurrent metastases, along with a literature review. A 65-year-old male patient underwent subtotal gastrectomy for advanced gastric adenocarcinoma. Six months after gastrectomy, 2 metastatic intra-abdominal lymph node enlargements were detected, which were treated with radiotherapy. At 55 months after gastrectomy, an abdominal wall mass was detected, which was treated by surgical resection. The patient received 5-fluorouracil/leucovorin/irinotecan chemotherapy for 27 months before and after radiotherapy and docetaxel chemotherapy for 6 months after surgical resection of the abdominal wall metastasis. At the last visit, 7.8 years since the initial resection of the primary gastric cancer and 6.2 years since detection of the first metastases, the patient was disease-free and required no further chemotherapy. This case suggests that repeated local therapy offers potential for long-term survival in a carefully selected subset of patients with recurrent metastases.

PURPOSE: This study aimed to assess complications and outcomes of a new approach, that is, combining short course radiotherapy (SRT), concurrent and consolidative chemotherapies, and delayed surgery. MATERIALS AND METHODS: In this single arm phase II prospective clinical trial, patients with T3-4 or N+ M0 rectal adenocarcinoma were enrolled. Patients who received induction chemotherapy or previous pelvic radiotherapy were excluded. Study protocol consisted of three-dimensional conformal SRT (25 Gy in 5 fractions in 1 week) with concurrent and consolidation chemotherapies including capecitabine and oxaliplatin. Total mesorectal excision was done at least 8 weeks after the last fraction of radiotherapy. Primary outcome was complete pathologic response and secondary outcomes were treatment related complications. RESULTS: Thirty-three patients completed the planned preoperative chemoradiation and 26 of them underwent surgery (24 low anterior resection and 2 abdominoperineal resection). Acute proctitis grades 2 and 3 were seen in 11 (33.3%) and 7 (21.2%) patients, respectively. There were no grades 3 and 4 subacute hematologic and non-hematologic (genitourinary and peripheral neuropathy) toxicities and perioperative morbidities such as anastomose leakage. Grade 2 or higher late toxicities were observed among 29.6% of the patients. Complete pathologic response was achieved in 8 (30.8%) patients who underwent surgery. The 3-year overall survival and local control rates were 65% and 94%, respectively. CONCLUSION: This study showed that SRT combined with concurrent and consolidation chemotherapies followed by delayed surgery is not only feasible and tolerable without significant toxicity but also, associated with promising complete pathologic response rates.
