OBJECTIVE: To investigate the effect of neoadjuvant chemotherapy on cervical carcinoma and its association with clinical data. METHODS: A total of 97 patients with stage Ib2 approximately IIIa of cervical cancinoma were treated with neoadjuvant chemotherapy. The effect of chemotherapy, factors associated with outcome of chemotherapy, and histology were analyzed. RESULTS: Effective rate of chemotherapy was 86.6% which was associated with clinical stage and histology. Eight-four patients received radical hysterectomy. The histological grade of 17 patients was lowered, lymph nodes in 19 patients were positive, and 6 patients had parametrium invasion. One patient died within 1 year after the operation, and 5 patients recurred. CONCLUSION The effect of neoadjuvant chemotherapy for locally advanced cervical cancinoma is good. Surgery after chemotherapy can improve the prognosis and 5-year survival rate.

BACKGROUND: Surgery was not standard-of-care of patients with advanced lung cancer. However, a serial of retrospective studies demonstrated that thoracic dissemination (M1a) patients could benefit from contraindicated surgery. After non-standard treatment, how should these patients choose following treatment approaches? Herein, we conducted this retrospective study to explore subsequent optimal treatment approaches. METHODS: Different therapeutic approaches were evaluated by comparing progression-free survival (PFS), overall survival (OS), time to treatment interval (TTI) using the Kaplan-Meier method and Log-rank test. A Cox proportional hazards regression model was used for multivariate analysis. RESULTS: 141 eligible were enrolled. The median PFS of chemotherapy group, targeted therapy group and observation group were 14.7, 41.0 and 31.0 months, respectively (95%CI: 19.01-26.01; P<0.001). There was no significantly statistically difference between median PFS of targeted group and observation group (P=0.006). The median OS were 39.0, 42.6 and 38.1 months (95%CI: 32.47-45.33; P=0.478). The median PFS and OS of TTI<3 months and TTI ≥3 months were 15.2 months versus 31.0 months (95%CI: 19.01-26.06; P<0.001) and 41.7 months versus 38.7 months (95%CI: 32.47-45.33; P=0.714). Multivariate analyses revealed gender (P=0.027), lymph node status (P=0.036) and initial therapy (P<0.001) were independent prognostic factors for PFS. CONCLUSIONS Observation did not shorten survival of thoracic dissemination patients with lung adenocarcinoma or squamous carcinoma, therefore, it could be an favorable option. But prospective randomized controlled study was needed to confirm its validity.

OBJECTIVETo evaluate the therapeutic effect of preoperative regional intra-arterial chemotherapy (PRAC) on progressive lower rectal cancer.

METHODSForty-five patients with progressive lower rectal cancer were divided into groups A (23 cases) and B (22 cases) for treatment with PRAC 1 to 2 weeks prior to surgical tumor resection or with surgical resection only, respectively.

RESULTSPRAC caused obvious tissue degeneration and necrosis of rectal cancer with a total effective rate of 95.65%. The rates of radical resection in groups A and B were 91.3% and 72.27%, respectively. The 1-year postoperative survival rates of the two groups were 95.65% and 86.36%, with 3-year survival of 89.96% and 68.18%, and 3-year postoperative recurrence rates of 8.69% and 27.27%, respectively. The anal preservation rates of the two groups were 78.26% and 59.09%.

CONCLUSIONPRAC can increase radical resection rates, promote the postoperative survival and anal preservation rate, and lower the recurrence rate in patients with lower rectal cancer.

Transglutaminase 2 (TG2), a cross-linking enzyme, is involved in drug resistance and in the constitutive activation of nuclear factor kappa B (NF-kappaB). We investigated the association of non-small cell lung cancer (NSCLC) treatment efficacy with TG2 and NF-kappaB expression in 120 patients: 102 with adenocarcinoma and 18 with other histologic types. All patients underwent surgery; 88 received adjuvant chemotherapy, with 28 receiving platinum-based doublet chemotherapy as first-line treatment and 29 receiving epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI) therapy. Patients' TG2 and NF-kappaB expression values were calculated semiquantitatively. The median TG2 value was 50 (range, 0-300) and the median NF-kappaB value was 20 (range, 0-240). Disease-free survival did not differ between the low- and high-TG2 groups. Among patients who received palliative platinum-based doublet chemotherapy, progression free survival (PFS) was longer in the low-TG2 group than in the high-TG2 group (11.0 vs. 7.0 months; P=0.330). Among those who received EGFR-TKI therapy, PFS was also longer in the low-TG2 group than in the high-TG 2 group (11.0 vs. 2.0 months; P=0.013). Similarly, in EGFR wild-type patients treated with EGFR-TKI, PFS was longer in patients with low TG2 expression (9.0 vs. 2.0 months; P=0.013). TG2 expression levels can predict PFS in patients with NSCLC treated with EGFR-TKI.

BACKGROUNDRegional intra-arterial infusion chemotherapy (RIAC) has been more valuable to improve prognosis and quality of life of patients with inoperable pancreatic adenocarcinomas, and adjuvant RIAC plays an important role in prolonging survival and reducing risk of liver metastasis after radical resection of pancreatic cancer, but the effect of preoperative or multiple-phase RIAC (preoperative combined with postoperative RIAC) for resectable pancreatic cancers has not been investigated. In this prospective study, the effect of multiple-phase RIAC for patients with resectable pancreatic head adenocarcinoma was evaluated, and its safety and validity comparing with postoperative RIAC were also assessed.

METHODSPatients with resectable pancreatic head cancer were randomly assigned to two groups. Patients in group A (n=50) were treated with new therapeutic mode of extended pancreaticoduodenectomy combined with multiple-phase RIAC, and those in group B (n=50) were treated with extended pancreaticoduodenectomy combined with postoperative RIAC in the same period. The feasibility, compliance and efficiency of the new therapeutic mode were evaluated by tumor size, serum tumor markers, clinical benefit response (CBR), surgical complications, mortality and toxicity of RIAC. The disease-free survival time, median survival time, incidence of liver metastasis, survival rate at 1, 2, 3 and 5 years were also observed. Life curves were generated by the Kaplan-Meier method.

RESULTSThe pain relief rate and CBR in group A was 80% and 84% respectively. Serum tumor markers decreased obviously and tumors size decreased in 26% of patients after preoperative RIAC in group A. No more surgical complications, mortality or severe systemic side effects were observed in group A compared with group B. The incidence of liver metastasis in group A was 34% which was lower than 50% in group B. The disease-free survival time and median survival time in group A were 15.5 months and 18 months respectively. The 1-, 2-, 3- and 5-year survival rates were 54.87%, 34.94%, 24.51% and 12.25% respectively. There was no significant difference of survival time or survival rates between two groups.

CONCLUSIONSMultiple-phase RIAC is effective in combined therapy of resectable pancreatic head carcinomas by enhancing inhibition of tumor growth and reduction of liver metastasis, without negative effect on patients' safety or surgical procedure.
