Background: Whether concurrent chemotherapy treatment is superior to radiotherapy alone as an adjuvant regimen for postoperative cervical carcinoma with risk factors remains controversial. Materials and Methods: A literature search strategy examined Pubmed, Embase, the Cochrane Library, the China National Knowledge Internet Web, the Chinese Biomedical Database and the Wanfang Database. Article reference lists and scientific meeting abstracts were also screened. Controlled trials comparing concurrent chemoradiotherapy versus radiotherapy alone in postoperative cervical cancer were included. The methodological quality of non-randomized controlled trials was evaluated using the Newcastle-Ottawa Scale. Randomized controlled studies were evaluated with the Cochrane handbook. A meta-analysis was performed with RevMan 5.3. Results: A total of 1,073 patients from 11 clinical trials were analysed, with 582 patients in the concurrent chemoradiotherapy group and 491 patients in the radiotherapy group. Hazard ratios (HR) of 0.47 (95% CI 0.31-0.72) and 0.50 (95% CI 0.35-0.72) were observed for overall survival and progression-free survival, indicating a benefit from the additional use of concurrent chemotherapy. Subgroup analyses demonstrated that cervical cancer with high risk factors significantly benefitted from concurrent chemotherapy when examining overall survival (HR 0.44, 95% CI 0.28-0.67) and progression-free survival (HR 0.48, 95% CI 0.33-0.70), but patients with intermediate risk factors showed no benefit from concurrent chemotherapy in overall survival (HR 1.72, 95% CI 0.28-10.41) and progression-free survival (HR 1.09, 95% CI 0.19-6.14). No significant differences were observed for grade 3-4 anaemia (risk ratio (RR) 3.87, 95% CI 0.69-21.84), grade 3-4 thrombocytopenia (RR 3.04, 95% CI 0.88-10.58), grade 3-4 vomiting or nausea (RR 1.71, 95% CI 0.27-10.96), or grade 3-4 diarrhoea (RR 1.40, 95% CI 0.69-2.83). Significant differences were observed for grade 3-4 neutropenia in favour of the radiotherapy group (RR 7.23, 95% CI 3.94-13.26). Conclusions: In conclusion, concurrent chemoradiotherapy improves survival in postoperative cervical cancer with high risk factors but not in those with intermediate risk factors.

The aim of this study was to evaluate prospectively the impact of the red ginseng extract on circulating interleukin (IL) 2 and 10 in advanced gastric cancer during chemotherapy after operative treatment. Analysis of circulating IL-2 and 10 was performed in 50 patients with advanced gastric adenocarcinoma who underwent a curative surgery or with an unresectable gastric adenocarcinoma by using ELISA and monoclonal antibodies at preoperative day 1, postoperative months 1, and 3. Twenty-five patients as the control group, twenty-six patients as the non-ginseng (NG) group, and twenty-four patients as the ginseng (G) group were eligible in this study. All plasma IL-2 of the NG and G groups was significantly lower an that of the control group on preoperative 1 day. These values of the G group were more increase than these of the NG group during the postoperative chemotherapy. The mean value of serum IL-10 of the control group (0.608pg/ml) was significantly lower than that of the advanced gastric cancer patients including the NG (12.015 pg/ml) and G group (9.409 pg/ml) (p＜0.001). These values of the G group were reduced progressively during the postoperative chemotherapy. The mesh value of the G group were only close to that of the control group on postoperative months 3 (p=0.003). The number of patients who were enrolled in this study was relatively small to fully evaluate the immunologic effects of the red ginseng extract on circulating IL-2 and 10. Despite this limitation, these results suggest that the post-operative intake of the red ginseng extract have potential to improve earlier anti-cancer immunity with recovering IL-2 and reducing IL-10 from the depressed IL-2 and elevated IL-10 by gastric cancer during the postoperative chemotherapy. This study will be based on the future study to evaluate the anti-immunity of the red ginseng extract.

Objective: To explore the clinical application of recombinant human endostatin (Endostar) in the treatment of patients with non-small cell lung cancer (NSCLC) in Chinese mainland. Materials and Methods: A total of 75 patients diagnosed as NSCLC were randomly divided into control group (37 cases) and treatment group (38 cases). Control group was treated with postoperative complementary chemotherapy containing two-agent platinum protocol on postoperative d21, 3 weeks as a cycle, for totally 4~6 cycles. On this basis, treatment group was added with Endostar $7.5mg/m^2$ on postoperative d8~9, 3~4 h/time, qd, 14 weeks as a cycle, for totally 4 cycles. The interval between every two cycles was 7 d. The 5-year progression-free survival (PFS), 5-year survival time and complications in both groups were observed. Results: Compared with control group, the average PFS increased evidently in treatment group by 9.8 months (41.6 months vs. 31.8 months), and there was significant difference (P<0.05). And the median PFS was 42.5 months in treatment group, obviously longer than that in control group (33.7 months) by 8.8 months (P<0.05). Additionally, the 5-year overall survival rate (OS), average survival time and median survival time (MST) were 47.4%, 50.1 months and 59.3 months in treatment group, significantly higher than the 29.7%, 42.1 months and 43.5 months in control group (P<0.05). Only 1 patient showed poor healing of surgical wound in treatment group, but no surgery-associated complication was found in control group. Moreover, the postoperative complementary therapy-connected complication rates were 63.2% (24/38) and 59.5% (22/37) in treatment group and control group respectively, but there was no significant difference (P>0.05). Conclusions: The application of Endostar combined with sensitive platinum-contained chemotherapeutic agents in the postoperative complementary chemotherapy can be widely used in clinic because it can significantly prolong the long-term survival time of patients with NSCLC.

Purpose: To evaluate the efficacy of conservative surgery plus chemo-, radio-therapy in treating patients with early stage breast cancer. Patients and Methods: Eligible patients were treated by postoperative chemotherapy as well as whole-breast irradiation with tumor bed boost. Postoperative radiotherapy consisted of 6 MV whole breast linear accelerator irradiation with two tangential half fields to a total dose of 45~50 Gy, followed by $10{\sim}15MeV{\beta}$ boost irradiation to tumor bed for 10~20Gy, total dose 56~66Gy. Results: Fifty-two patients were enrolled. Overall 1-, 2- and 3 year survival rates were 98.1%, 92.3%, and 90.4%, respectively, with a local recurrence rate of 5.77%. Cosmetic results were evaluated as good by doctors in 90.4% of patients. Conclusions: Breast conservative surgery combined with chemo- radio-therapy could be a treatment option for Chinese patients with early stage breast cancer.

The purpose of this study was to determine if international guidelines differ in their recommendations concerning additive therapy for advanced, but potentially curable, gastric cancer. A systematic search of the English and German literature was conducted in the databases Medline, Cochrane Database, Embase, and PubMed. The search terms used were 'guidelines gastric cancer,' 'guidelines stomach cancer,' and 'Leitlinien Magenkarzinom.' Six different guidelines published after January 1, 2010, in which the tumors were classified according to the seventh edition of the TNM system (2010), were identified. Although the examined guidelines were based on the same study results, their recommendations concerning accompanying therapy for gastric cancer differ considerably. While perioperative chemotherapy is recommended in Germany, Great Britain, and large parts of Europe, postoperative adjuvant radiochemotherapy or perioperative chemotherapy is recommended in the USA and Canada. In Japan, postoperative adjuvant chemotherapy is recommended. The results of identical studies were interpreted differently in different countries. Since considerable effort is required for each country to separately test relevant studies for their validity and suitability, an international cooperation could simplify the creation of a common basis for guidelines and contribute to improved comparability of international guidelines.

Purpose : To assess the efficacy and toxicity of the preoperative radiotherapy with or without chemotherapy in locally advanced rectal cancer Methods : Forty three patients (clinically diagnosed stages above or equal to Astler-Coiler stage B2 without distant metastasis) were assigned to preoperative radiotherapy alone arm (n=16) or combined preoperative radiotherapy and chemotherapy arm (n=27). Preoperative radiotherapy of 4500 cGy to whole pel-vis +/-540 cGy boost to primary site and concurrent chemotherapy of 2 cycles of 5-FU (500 mg/$m^2$) and leucovorin (20 mg/$m^2$) were used. Fifteen patients of preoperative radiotherapy alone arm and 19 of combined arm received surgical resection after preoperative treatment. Results : During the preoperative treatment, no significant complication was developed in both groups. Pathologic results were as follows; complete remission 1, Bl 1, B2 6, C1 2, C2, 5 in preoperative radiotherapy alone arm and complete remission 2, Bl 8, B2 4, C2 3, D 2 in combined arm. Postoperative complications were delayed perineal wound healing in three patients, intestinal obstruction in three patients (one managed by conservative medical treatment, two by surgical treatment). Conclusion : The combined preoperative radiotherapy and chemotherapy arm was more effective in pathological response and lymph node negativity rate than the preoperative radiotherapy alone arm. Both the preoperative radiotherapy alone arm and the combined arm were generally well tolerated and did not result in an increased postoperative morbidity.

A significant proportion of patients with non-small cell lung cancer (NSCLC) is diagnosed in the early and resectable stage. Despite the use of platinum-based adjuvant chemotherapy, there was only a marginal increase in overall survival and a 15% decrease in relapse. With the advents of immunotherapy and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), the landscape of adjuvant treatment in completely resectable NSCLC is changing. Postoperative radiotherapy can be beneficial to patients who underwent surgical resection in certain clinical settings. In addition, new biomarkers that predict efficacy of EGFR TKI and immunotherapy as adjuvant treatment are also necessary. In this review, recent updates in adjuvant treatment in resectable NSCLC were briefly explained.

Purpose: Patients experiencing chemotherapy-induced peripheral neuropathy (CIPN) apply various palliative care as well as drugs in their daily life to alleviate symptoms. There is a need to identify the influence of these efforts and patients' psychosocial status on the relief of CIPN symptoms. This short-term prospective study investigated how prescription drugs, non-pharmacological behaviors (exercise, massage, and heat therapy), and psychological states (social support, depression, and anxiety) affected CIPN symptoms. Methods: Participants scheduled to receive postoperative platinum or taxane-based chemotherapy were enrolled consecutively. CIPN was measured with the Neurotoxicity-12 subscale of the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity-12 instrument. Data were collected three times during the 4 or 5 cycles of chemotherapy. Results: At the end of the 2nd chemotherapy cycle, 93.1% of participants reported CIPN symptoms. Multiple regression analyses showed that a heat therapy (β= -.34, p< .001), massage (β= -.21, p= .012), and walking 5 times or more per week (β= -.26, p= .021) provided relieve for CIPN symptoms. Depression (β= .19, p= .027) significantly exacerbated CIPN symptoms. Conclusion: These results suggested that a comprehensive management program that includes walking, heat therapy, massage, and mood therapy should be encouraged. Moreover, patients should be educated at chemotherapy initiation to understand appropriate interventions that can relieve CIPN symptoms.

The role of adjuvant chemotherapy in patients with stage II colon cancer remains a controversial issue. Adjuvant chemotherapy aims to eliminate any micrometastatic disease that may have been missed, at the time of surgery. Although one prospective study showed a small but statistically significant benefit with respect to the overall survival for those who received adjuvant chemotherapy, multiple pooled data did not demonstrate any benefit of this therapy in patients with stage II colon cancer. Current national and international guidelines for the adjuvant treatment of stage II colon dose not advise routine implementation of adjuvant chemotherapy, but rather recommend selective use of this therapy for patients with high risk of recurrence. High risk features for recurrence include T4 disease, poorly differentiated histology, presence of lymphovascular invasion, presence of perineural invasion, inadequate retrieval of lymph nodes, bowel obstruction, localized perforation, or positive margins. More recently, prediction tools using gene expression cancer profiles are proposed to identify patients who are most likely to have recurrence and therefore may benefit from postoperative chemotherapy in stage II colon cancer. These novel methods together with conventional prognosticators, will allow us to implement more optimized personalizing adjuvant therapy in these patients.

Despite of mortality and morbidity rates that are higher than other forms of therapy, surgical resection has been mainstay for the treatment of esophageal cancer because of a prompt completeness as well as a high possibility of cure. But a substantial numbers of patients are unsuitable for surgical treatment and those undergoing resection have still poor long term survival rate. With hopes of improving long term survival, we have attempted multimodal approach, composed of preoperative induction chemotherapy utilizing Cisplatin and 5 \ulcornerFU, surgery and postoperative loco-regional radiotherapy for the treatment of esophageal cancer since 1985. During the period of 1967 \ulcorner1985, 27 patients[group A] were treated by surgery only and during recent 5 years 28 patients[group B] by multimodal treatment, Clinical review and comparison between the two groups were as follows: l. Applied surgical procedures were hand-sewn esophagogastrostomy, esophagocologastrostomy and esophagojejunostomy in group A. In group B, only esophagogastrostomy was underwent using stapler mainly. 2. Incidence of peri and postoperative complication showed no remarkable differences between the two groups, but the occurrences of leakage from the anastomotic site were 5[19% ] out of group A and 1[4%] out of group B. 3. The response rate to induction chemotherapy was 36% in group B, 4. The number of local cancer recurrence at the site of anastomosis was 6[22%] out of group A, whereas 2[7%] out of group B. 5. Postoperative I year and 2 year survival were 61%, 15% in group A and 75%, 42% in group B.
