OBJECTIVETo investigate the association of nutritional status with treatment compliance and toxicities in patients undergoing chemoradiation therapy (CRT) after gastrectomy.

METHODSFrom September 2010 to May 2012, 40 patients with gastric cancer received adjuvant CRT in the Department of Radiation, Shanghai Cancer Center. Data including clinical data, weight loss of perioperative period, dynamic changes of weight, NRS 2002 score, PG-SGA score, lymph cell count and serum albumin during CRT, toxic effects and nutritional interventions were collected. Treatment compliance of CRT and adjuvant chemotherapy was recorded. Associations among nutrition, toxicities and treatment compliance were statistically studied.

RESULTSWeight loss percentage from pre-operation to pre-CRT(T1-T2) was 10.0%, which was significantly higher than that of 4.3% during CRT(T3) (P<0.05). Adverse reaction incidence of digestive tract during T3 was 95.0% (38/40). Patients with weight loss >5% during T3 had higher ratio of >II degree digestive tract adverse reaction [91.3% (21/23) vs. 76.5% (13/17), P<0.01] and higher ratio of >3 symptoms of digestive tract[82.4% (14/17) vs. 39.1% (9/23), P<0.05] as compared to those with weight loss ≤5% during T3. Fourteen patients (35.0%) did not complete the synchronous CRT. Factors related to incompletion of CRT were weight loss >7% after surgery (T1) or >10% during T1-T2, malnourishment before CRT, dependence on nutritional support during CRT. Factors related to incompletion of adjuvant chemotherapy were weight loss >5% during CRT(T3), requirement for nutritional support and NRS 2002 score ≥5 at the end of radiation (all P<0.05).

CONCLUSIONSNutritional deterioration before CRT may aggravate the toxicities and reduce compliance of CRT in patients with radical resection of gastric cancer. Malnutrition during CRT may impair compliance to adjuvant chemotherapy. Therefore, early and persistent nutritional interventions are crucial considerations of strategies of multidisciplinary treatment for patients with gastric cancer.

OBJECTIVETo evaluate the clinical efficacy of the ARAR0331 protocol for treatment of childhood nasopharyngeal carcinoma.

METHODSThe clinical data of eight children with nasopharyngeal carcinoma between May 2004 and May 2012 were retrospectively studied. The eight patients included six boys and two girls, and the onset age was between 3 and 13 years. Six patients were in AJCC Stage Ⅲ, one was in StageⅡA and one was in Stage ⅣA. One patient had been treated with combined radiotherapy and chemotherapy which mainly included EAP, BEP and EA. The other seven patients had been treated with the ARAR0331 protocol provided by the America Children's Oncology Group (COG).

RESULTSThe patient who had been treated with combined radiotherapy and chemotherapy developed multiple bony metastasis during the chemotherapeutic period. Four out of seven patients who had been treated with ARAR0331 protocol achieved complete remission, and two achieved partial remission. The seven patients were followed-up from 8 to 75 months and the survival rate was 100%. The ARAR0331 protocol treatment-related complications included radiodermatitis, mucocitis and nausea. Late toxicity was not found.

CONCLUSIONSBased on the limited cases, ARAR0331 protocol appears to be effective and safe for childhood nasopharyngeal carcinoma.

Gastrointestinal cancer and related treatments (surgery and chemoradiotherapy) are associated with declined functional status (FS) that has impact on quality of life, clinical outcome and continuum of care. Psychological distress drives an impressive burden of physiological and psychiatric conditions in oncologic care. Cancer patients often experience anxiety, depression, low self-esteem and fears of recurrence and death. Cancer prehabilitation is a process from cancer diagnosis to the beginning of treatment, which includes psychological, physical and nutritional assessments for a baseline functional level, identification of comorbidity, and targeted interventions that improve patient's health and functional capacity to reduce the incidence and the severity of current and future impairments with cancer, chemoradiotherapy and surgery. Multimodal prehabilitation program encompasses a series of planned, structured, repeatable and purposive interventions including comprehensive physical exercise, nutritional therapy, and relieving anxiety and depression, which integrates into best perioperative management ERAS pathway and aims at using the preoperative period to prevent or attenuate the surgery-related functional decline, to cope with surgical stress and to improve the consequences. However, a number of questions remain in regards to prehabilitation in gastrointestinal cancer surgery, which consists of the optimal makeup of training programs, the timing and approach of the intervention, how to improve compliance, how to measure functional capacity, and how to make cost-effective analysis. Therefore, more high-level evidence-based studies are expected to evaluate the value of implementation of prehabilitation into standard practice.

To investigate the clinical efficacy of consolidation chemotherapy with docetaxel and cisplatin (DP) in elderly patients of esophageal cancer.
 Methods: Seventy-nine elderly patients of esophageal cancer were randomly divided into the treatment group (38 patients) and the control group (41 patients). Intensity modulated radiation therapy (IMRT) was applied in both groups and prescribed dose was set to 56 to 59.4 Gy in 28 to 33 fractions. The concurrent chemotherapy regime for both groups was as follow: docetaxel 25 mg/m2 plus cisplatin 25 mg/m2, per week. After concurrent chemoradiotherapy, consolidated chemotherapy was applied to the treatment group with docetaxel 60 mg/m2 and cisplatin 75 mg/m2 
for 3 weeks in one cycle. There was no subsequent treatment for the control group.
 Results: The clinical efficacy was assessed in 76 patients. For the treatment group, 31 patients (response rate, 89.2%) obtained effective response, including 10 cases with complete response (CR) and 21 cases with partial response (PR), both of which were significantly more than that in the control group (response rate, 61.5%), with 9 cases of CR and 15 cases of PR. The median progression-free survival was 19.7 months in the treatment group, clearly longer than that in the control group (10.8 months, P=0.04). The overall survival for 1-year, 2-year and 3-year were 78.5%, 57.9% and 37.8% in the treatment group versus 61.2%, 42.3% and 22.7% in the control group (P>0.05), respectively. Grade 1 and 2 adverse effects were commonly observed in both groups, such as hematologic toxicity and radiation-induced esophagitis, but there was no significant difference between the two groups. 
 Conclusion: For elderly patients with esophageal carcinoma, the overall response rate can be significantly improved by concurrent chemoradiotherapy with subsequently consolidated chemotherapy based on docetaxel and cisplatin..

BACKGROUND AND OBJECTIVEConcurrent chemoradiation therapy (CCRT) is the standard treatment for patients with locally advanced nasopharyngeal carcinoma (NPC). The effect of neoadjuvant chemotherapy followed by CCRT has not been determined. Therefore, we conducted 2 phase II studies to evaluate the efficacy and safety of neoadjuvant chemotherapy with a regimen of docetaxel, cisplatin, and 5 fluorouracil (5-Fu) (TPF) followed by radiotherapy and concurrent cisplatin in patients with stage III and IV(A - B) NPC. This article is the preliminary report on treatment related toxicities and response.

METHODSGraded according to the 2002 American Joint Committee on Cancer (AJCC) staging criteria, only patients with stage III or IV(A-B) poorly differentiated or undifferentiated NPC (World Health Organization type II/III) were included. We planned to recruit 52 patients with stage III disease and 64 patients with stage IV(A - B) disease. All patients received neoadjuvant chemotherapy with TPF (docetaxel 75 mg/m(2), day 1; cisplatin 75 mg/m(2), day 1; 5 Fu 500 mg/(m2 x day), continuous intravenous infusion for 120 h), every 3 weeks for 3 cycles, followed by weekly cisplatin (40 mg/m(2)) concurrent with radiotherapy. Three dimensional conformal radiotherapy (3D CRT) and intensity modulated radiotherapy (IMRT) were used. Gross disease planning target volume (PTV), high risk and low risk subclinical PTV doses were prescribed at 70-76 Gy, 66-70 Gy, and 60-61.25 Gy at 1.75-2.0 Gy per fraction. The lower neck or supraclavicular fields may be treated with conventional AP/PA fields for a total of 54 Gy at 1.8 Gy per fraction. Patients were evaluated for tumor response after the completion of neoadjuvant chemotherapy, and at 3 months after radiation according to the Response Evaluation Criteria In Solid Tumors (RECIST). The latest version of the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI CTCAE 3.0) was used for grading all adverse events.

RESULTSFifty nine patients were evaluable for treatment response. Thirty patients had stage III disease and 29 patients had stage IV(A-B). All patients completed RT to the prescribed dose and 2 cycles of neoadjuvant chemotherapy, with 51 patients (86.4%) completing 3 cycles. A total of 50 (84.7%) and 39 patients (66.1%) completed 4 weeks and 5 weeks of cisplatin during CCRT, respectively. The overall response rate in the primary site and the neck region were 94.9% [complete response (CR) in 25.4%] and 100% (CR in 19.6%) after completing neoadjuvant chemotherapy. At 3 months after RT, the CR rates increased to 96.6% and 90.2%, respectively. After a median follow up of 14.3 months, we observed 5 treatment failures and 2 deaths. The 1 year overall survival, distant metastasis free survival, and locoregional relapse free survival rates were 100%, 95.7%, and 97.7%, respectively. The rates of grade 3/4 myelosuppression and anorexia/nausea/vomiting during neoadjuvant chemotherapy were 55.9% and 16.9%, respectively. The corresponding rates were 11.9% and 23.7% during CCRT. Grade 3/4 mucositis, skin desquamation, and xerostomia occurred in 6.8%, 44.1%, and 27.1% of patients, respectively. There were no treatment related deaths.

CONCLUSIONSNeoadjuvant chemotherapy with TPF followed by CCRT was well tolerated with a manageable toxicity profile. Preliminary results are encouraging and warrant further investigation.

OBJECTIVETo analyze the clinical features and risk factors of anastomotic leakage after radical esophagectomy of esophageal carcinoma.

METHODSThe clinical data of 547 esophageal cancer patients underwent radical esophagectomy in Tianjin Medical University Cancer Hospital from January 2012 to December 2013 was analyzed retrospectively. There were 421 male and 126 female patients, with a median age of 65 years (ranging from 29 to 82 years). There were 155 cases of upper esophageal carcinoma, 340 cases of middle esophageal carcinoma and 52 cases of lower esophageal carcinoma. The surgical procedures included 41 cases completed through Sweet, 145 cases completed through McKeown, 279 cases completed through Ivor Lewis, 82 cases completed through minimally invasive esophagectomy. Moreover, 24 of 547 cases underwent preoperative neoadjuvant radiochemotherapy. χ² test and Cox's proportional hazards regression model were used for univariate analysis and multivariate analysis of the risk factors of postoperative anastomotic leakage.

RESULTSTwenty-seven of 547 cases with esophagectomy occurred anastomotic leakage and the incidence rate was 4.94% (27/547). One of 27 cases died and the mortality rate was 3.70% (1/27). The time of anastomotic leakage found was 4 to 45 days, with a median time of 10 days. There were 0 case of early leakage, 20 cases of mid-term leakage, 7 cases of late leakage. Three of 27 cases with anastomotic leakage had tracheoesophageal fistula, while 3 cases had contralateral pleural fistula. As to the incidence rate of anastomotic leakage, there was statistically significant difference between cervical anastomotic leakage (8.14%, 18/221) and intrathoracic anastomotic leakage (2.76%, 9/326) (χ² =7.41, P=0.000), among Sweet (4.88%, 2/41), McKeown (9.66%, 14/145), Ivor Lewis (2.51%, 7/279) and MIE (4.88%, 4/82) (χ² =21.48, P=0.000), and between with (16.67%, 4/24) and without (4.40%, 23/523) neoadjuvant radiochemotherapy (χ² =9.20, P=0.000). The multivariate analysis showed that anastomotic site (HR=2.594, P=0.048), surgical approach (HR=5.689, P=0.003) and preoperative neoadjuvant radiochemotherapy (HR=3.604, P=0.027) are independent risk factors for anastomotic leakage after esophagectomy.

CONCLUSIONSThe mid-term anastomotic leakage after esophagectomy occurs higher. McKeown is a main surgical procedure and neoadjuvant radiochemotherapy is an important factor for the anastomotic leakage.

OBJECTIVETo assess the effect of Qingfei Quyu Decoction (QQD) in preventing radiation pneumonitis in esophageal carcinoma patients by concurrent using it with chemoradiotherapy.

METHODSA total of 120 patients with mid-late stage esophageal carcinoma were randomly assigned to the treatment group (60 cases) and the control group (60 cases). All patients received concurrent radiochemotherapy. Patients in the treatment group additionally took QQD, one dose per day for 8 successive weeks. The incidence of radiation pneunonitis was compared between the two groups. The improvement rates of short-term benefit rate, Karnofsky performance scale (KPS), and body weight (BW) improvement rate were calculated between the two groups. The 1-and 2-year overall survival rates were compared between the two groups.

RESULTSThe incidence of radiation pneunonitis was 8.93% (15/56) in the treatment group and 18.64% (11/59) in the control group (P < 0.05). The short-term benefit rate was 92.86% (52/56) in the treatment group and 69.49% (41/59) in the control group (P < 0.05). Besides, the KPS and BW improvement rate were higher in the treatment group [89.29% (50/56) and 83.05% (49/59) ] than in the control group [80.36% (45/56) and 66.10% (39/59)] (P < 0.05). The 1-and 2-year overall survival rate were 66.07% and 35.71% in the treatment group, higher than those of the control group (61.02% and 30.51%; P > 0.05).

CONCLUSIONConcurrent using QQD with chemoradiotherapy for treating esophageal carcinoma patients could lower the incidence of radiation pneumonitis, attenuate the degree of radiation induced lung injury, improve clinical benefit rate, and elevate their QOL.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

Objective: This study aims to investigate the associations between genetic variations of pyroptosis pathway related key genes and adverse events (AEs) of postoperative chemoradiotherapy (CRT) in patients with rectal cancer. Methods: DNA was extracted from the peripheral blood which was collected from 347 patients before CRT. Sequenom MassARRAY was used to detect the genotypes of 43 haplotype-tagging single nucleotide polymorphisms (htSNPs) in eight pyroptosis genes, including absent in melanoma 2 (AIM2), caspase-1 (CASP1), caspase-4(CASP4), caspase-5 (CASP5), caspase-11 (CASP11), gasdermin D (GSDMD), gasdermin E (GSDME) and NLR family pyrin domain containing 3 (NLRP3). The associations between 43 htSNPs and AEs were evaluated by the odd ratios (ORs) and 95% confidence intervals (CIs) by unconditional logistic regression models, adjusted for sex, age, clinical stage, tumor grade, Karnofsky performance status (KPS), surgical procedure, and tumor location. Results: Among the 347 patients with rectal cancer underwent concurrent CRT with capecitabine after surgery, a total of 101(29.1%) occurred grade ≥ 2 leukopenia. rs11226565 (OR=0.41, 95% CI: 0.21-0.79, P=0.008), rs579408(OR=1.54, 95% CI: 1.03-2.29, P=0.034) and rs543923 (OR=0.63, 95% CI: 0.41-0.98, P=0.040) were significantly associated with the occurrence of grade ≥ 2 leukopenia. One hundred and fifty-six (45.0%) had grade ≥ 2 diarrhea, two SNPs were significantly associated with the occurrence of grade ≥ diarrhea, including CASP11 rs10880868 (OR=0.55, 95% CI: 0.33-0.91, P=0.020) and GSDME rs2954558 (OR=1.52, 95% CI: 1.01-2.31, P=0.050). In addition, sixty-six cases (19.0%) developed grade ≥2 dermatitis, three SNPs that significantly associated with the risk of grade ≥2 dermatitis included GSDME rs2237314 (OR=0.36, 95% CI: 0.16-0.83, P=0.017), GSDME rs12540919 (OR=0.52, 95% CI: 0.27-0.99, P=0.045) and NLRP3 rs3806268 (OR=1.51, 95% CI: 1.03-2.22, P=0.037). There was no significant difference in the association between other genetic variations and AEs of rectal cancer patients (all P>0.05). Surgical procedure and tumor location had great impacts on the occurrence of grade ≥2 diarrhea and dermatitis (all P<0.01). Conclusion: The genetic variants of CASP4, CASP11, GSDME and NLRP3 are associated with the occurrence of AEs in patients with rectal cancer who received postoperative CRT, suggesting they may be potential genetic markers in predicting the grade of AEs to achieve individualized treatment of rectal cancer.

BACKGROUND AND OBJECTIVEMany patterns of treatment have been used to treat esophageal carcinoma in the past years, however, an optimal treatment is still the key issue to be explored. Therefore, we analyzed the published literature about radiotherapy for esophageal cancer in recent 15 years in China, and observed the survival rate, local control rate, adverse events, and so on.

METHODSA total of 56 eligible papers about radiotherapy for esophageal squamous cell carcinoma published in Chinese core periodicals between 1994 and 2009 were selected. The survival rates, local control rates, and adverse events were analyzed.

RESULTSThe 1-, 2-, 3-, and 5-year overall survival rates of the patients reported in the 56 papers were (67.99 ± 12.55)%, (49.59 ± 11.79)%, (34.50 ± 11.49)%, and (23.31 ± 10.21)%, respectively. The 1-, 2-, 3-, and 5-year local control rates were (73.04 ± 13.37)%, (61.60 ± 15.50)%, (51.77 ± 15.00)%, and (50.15 ± 21.36)%, respectively. The acute esophageal toxicity rate was (44.84 ± 25.71)% in 32 papers reported in recent 15 years, and the acute esophageal toxicity over grade II accounted for (35.93 ± 22.90)%. The rates of acute esophageal toxicity were (26.84 ± 13.12)% for conventional radiation, (53.72 ± 21.82)% for late course accelerated hyperfractionation radiation, (61.33 ± 28.69)% for concurrent chemoradiotherapy, and (40.31 ± 27.22)% for other ways of radiation. The late toxicity rate described in 23 papers was (5.13 ± 4.07)% in recent 15 years. The late toxicity rates were (5.66 ± 3.42)% for conventional radiation, (4.53± 4.07)% for late course accelerated hyperfractionation radiation, (2.24±1.31)% for concurrent chemoradiotherapy, and (7.34 ± 5.06)% for other ways of radiation. The Meta analysis indicated that concurrent chemoradiotherapy was better than late course accelerated hyperfractionation radiation and conventional radiation.

CONCLUSIONSThe long-term survival of patients with esophageal cancer is still disappointed in recent years. Concurrent chemoradiotherapy shows advantages in treating esophageal cancer and, currently, is the best non-surgical treatment of esophageal cancer.
