Objective To observe the early efficacy and toxicity of gemcitabine plus tegafur, gimeracil and oteracil potassium (S-1) regimen (GS regimen) in patients with metastatic castration-resistant prostate cancer (mCRPC) after docetaxel failure. Methods From July 2013 to December 2015, sixteen mCRPC patients who failed in the treatment of docetaxel-based chemotherapy in West China Hospital of Sichuan University were collected. And the patients were treated with gemcitabine 1 000 mg/m2 intravenously on Day 1 and S-1 40–60 mg/m2 orally dividedly twice daily on Day 1–10, which repeated every two weeks. The main outcome measures were total prostate-specific antigen (T-PSA) decline rate and pain remission rate. Results Of the 13 evaluable patients, the T-PSA decline rate≥50% was observed in 4 patients (30.8%). Among the 11 patients with bone pain, remarkable pain relief was observed in 4 cases (36.4%). Myelosuppression, gastrointestinal reaction, rash and fatigue were the commonly observed adverse reactions and the toxicity of chemotherapy was tolerable. Conclusion The GS regimen is active and tolerable in patients with mCRPC after docetaxel failure.
Objective To investigate the changes of thyroid hormone level in patients with nonsmall cell lung cancer ( NSCLC) before and after chemotherapy and its clinical significance.Methods 78 cases of NSCLC admitted between January 2009 and December 2011 were recruited in the study. The level of total triiodothyronine ( TT3 ) , total thyroxine ( TF4 ) , free triiodothyronine ( FT3 ) , free thyroxine ( FT4 ) , and thyroid stimulating hormone ( TSH) were measured by radioimmunoassay before and after chemotherapy. 35 normal subjects were recruited as control.Results The levels of TT3 [ ( 1. 27 ±0. 36) nmol /L vs. ( 2. 62 ±0. 46) nmol /L] and FT3 [ ( 2. 65 ±0. 76) pmol /L vs. ( 3. 79 ±0. 63) pmol /L] in the NSCLC patients were significantly lower than those in the controls ( P lt;0. 05) , while the levels of TT4 , FT4 and TSH were similar to the controls. The level of TT3 and FT3 were correlated with clinical stage ( P lt; 0. 05) , and not with histological grade and pathological type ( P gt;0. 05) . The levels of TT3 and FT3 were remarkably increased in complete remission or partial remission patients after chemotherapy ( P lt; 0. 05) . Conclusion Thyroid hormone measurement may be useful in the patients condition judgment and therapeutic effect monitoring.
ObjectiveTo observe the clinical characteristics of rhegmatogenous retinal detachment (RRD) secondary to conservative therapy in retinoblastoma (RB) patients.MethodsA retrospective study. From July 2013 to May 2017, 20 RRD patients (20 eyes) of 456 RB patients (573 eyes) treated in Xinhua Hospital of Shanghai Jiao Tong University School of Medicine were included in the study. Eleven patients (11 eyes) were boy and 9 patients (9 eyes) were girls. Thirteen patients demonstrated bilateral RB and 7 patients had unilateral RB. Average age when diagnosed with RB was 25 months. International Classification of Retinoblastoma groups were C in 1 eye, D in 17 eyes, and E in 2 eyes. These patients received intra-arterial chemotherapy (17 eyes), intravenous chemotherapy (11 eyes), intravitreal chemotherapy (8 eyes), laser (14 eyes) and/or cryotherapy (5 eyes). Twelve patients (12 eyes) received vitreoretinal surgery including vitrectomy (6 eyes) and scleral buckling (7 eyes). The mean follow-up was 39 months. Fundus examination was performed under general anesthesia during comprehensive treatment and follow-up. The time interval of fundus examination varied from 1 to 6 months depending on the stability of the tumor.ResultsRRD was noted in 20 eyes (3.5%) with RB. Retinal hole was found in 15 eyes (75%). The cause of RRD was atrophic hole in calcified tumor (6 eyes, 30%), cryotherapy-related hole (5 eyes, 25%) and laser-related hole (9 eyes, 45%). Multiple atrophic hole in calcified tumor was noted in 3 eyes. Size of hole smaller than 2 DD was noted in 8 eyes (53%), and larger than 2 DD was noted in 7 eyes (47%). Holes were in posterior (3 eyes), equator (2 eyes) and periphery (10 eyes). Severe proliferated was noted in 1 eye. No tear was found. No bulbar retinal detachment and choroidal detachment was noted. Among 12 eyes who underwent vitreoretinal surgery, reattachment was achieved in 9 eyes (75%). No metastasis was noted.ConclusionsCalcified regression of tumor, cryotherapy and laser were main reasons of RRD. Most of the holes are small in diameter and located in the periphery.
ObjectiveTo evaluate the efficacy of intra-arterial chemotherapy (IAC) for advanced retinoblastoma (RB) after failure of intravenous chemotherapy (IVC). MethodsFifteen eyes of 13 patients with advanced RB were treated with IAC (1-5 cycles) after failure of IVC (2-8 cycles). The patients included 10 boys and 3 girls, with the mean age of (15.67±8.16) months. Six patients had bilateral RB and 7 patients had unilateral RB. There were 14 eyes (93.33%) in stage D, 1 eye (6.67%) in stage E according to the International Classification of intraocular retinoblastoma. The main reasons for failure of IVC were recurrent primary tumor in 3 eyes (20.00%), subretinal seeds recurrence in 9 eyes (60.00%), viable vitreous seeds in 2 eyes (13.33%) and poor response of primary tumor in 1 eye (6.67%). The mean interval between IVC completion and IAC start was 3 months. The mean follow-up was 19 months (ranged from 3 to 52 months). ResultsAfter IVC and secondary IAC, the retinoblastoma and seeds were regressed in 12 eyes (80.00%). Three eyes required enucleation for severe vitreous seeds, subretinal seeds recurrence and primary tumor recurrence. There was no evidence of metastasis in any case. ConclusionIAC can achieve high global salvage rate (80.00%) for patients with advanced retinoblastoma after failure of IVC.
Objective To investigate the clinical efficacy and safety of hyperthermic intraperitoneal perfusion chemotherapy (HIPC) in treatment of advanced colorectal cancer.Methods The Meta-analysis was applied to analyze 8 randomized controlled quantitative studies published at domestic and abroad. These patients treated by HIPC after radical operation with colorectal cancer were included for the treatment group, and those treated only by radical operation with colorectal cancer for the control group. Relative risk (RR) of outcome variable of 3-year and 5-year survival rate and safety between the two groups were compared. Results There were 8 selected literatures, including 1 501 cases, in which 765 cases for treatment group, and 736 cases for control group. RR of 5-year survival rate of the total patients was 2.39 (95% CI: 1.66-3.45). RR of 3-year survival rate of the total patients was 2.13 (95% CI: 1.45-3.13). The results demonstrated that HIPC could improve 5-year and 3-year survival rate, and sensitivity analysis confirmed the conclusions more reliable. The security was described in 5 literatures, the available information showed smaller potential security issue. Conclusions HIPC after radical operation of advanced colorectal cancer can increase 5-year and 3-year survival rate of patients, improve the prognosis of patients. Whether patients with increased incidence of postoperative complications related to the HIPC is no clear-cut conclusions for lack of related research.
Nowadays, one of the most challenging aspects of retinoblastoma (RB) therapy is how to control the resistant or recurrent viable vitreous seeds, for which intravenous chemotherapy appears to be ineffective. Recently, intravitreal chemotherapy offers another option to control advanced stage and vitreous seeds of RB, and may be a promising new approach to RB therapy. However, intravitreal injection for RB patients raises considerable controversy due to concerns of possible extraocular extension along the injection route, and should not replace the primary standard of care for bilateral RB or group E eyes of RB. Close follow-up and further studies are needed to determine appropriate indications, to determine the effective drugs and concentrations, to optimize RB therapy protocols and to investigate the relationship between long-term efficacy and toxicities.
Intra-arterial chemotherapy (IAC) is an interventional treatment for retinoblastoma (RB) which infuses the chemotherapeutic agents through ophthalmic artery using microcatheters to control the tumor. Compared with systemic chemotherapy, IAC could significantly increase the globe salvage of advanced and recurrent RB without serious adverse event. Due to the absence of systemic absorption after IAC, no longer effectively kill tumor cell, which have potential danger to leads to inadequate elimination extraocular tumor cells. The most common systemic complications following IAC is myelosuppression; local ocular toxicities include eyelid edema, delacrimation, blepharoptosis, vitreous hemorrhage, retinal artery obstruction. During the last 10 years of clinical application, IAC become one of first-line treatment for intraocular RB. However, at present, there is still a lack of randomized controlled multicenter studies and long-term follow up of IAC.
Objective To assess effectiveness of chemotherapy versus non-chemotherapy in the treatment of soft tissue sarcoma. Methods We searched MEDLINE (1966 to Dec. 2008), EMBASE (1984 to Dec. 2008), OVID (1980 to Dec. 2008), CBMdisc (1980 to Dec. 2008), and the Cochrane Central Register of Controlled Trials. We also handsearched Journal of Chinese Oncology, Journal of Chinese Clinical Oncology, and Tumor (from inception to Dec. 2008). The quality of the included studies was evaluated by two reviewers independently and meta-analysis was performed for results of the homogenous studies. Results Six studies involving 836 participants related to primary, high grade, nonmetastatic soft tissue sarcoma were included. All included studies were unclear in reporting randomization and blinding; all studies reported the number and the reason of withdraw; and baseline conditions of all studies were compared. The results of meta-analyses showed that there were no significant differences in 5-year overal survival (RR=0.90, 95%CI0.76 to 1.06), local recurrence (OR=0.69, 95%CI 0.36 to 1.32), distant recurrence (OR=0.83, 95%CI 0.62 to 1.11), and overall recurrence (RR=0.91, 95%CI 0.78 to 1.06) between the chemotherapy group and the control group. But as to 5-year disease-free survival, the chemotherapy group was better than the control group (RR=0.73, 95%CI 0.63 to 0.86). Conclusion There is no advantage for the chemotherapy group over the control group in 5-year overal survival, local recurrence, distant recurrence and overall recurrence. Due to the risk of selection bias, performance bias and published bias, the evidence is not b enough to judge whether chemotherapy is better than control in treating soft tissue sarcoma. Our conclusion suggests that larger-scale randomized trials should be performed in future.
Objective To assess the effectiveness and safety of nedaplatin combined with 5-fluorouracil (5-Fu) for advanced esophageal cancer. Methods Such databases as PubMed, The Cochrane Library, EMbase, CBM, CNKI, VIP and WanFang Data were searched from the date of their establishment to May 4th, 2012 to collect the randomized controlled trials (RCTs) about nedaplatin combined with 5-Fu versus cisplatin combined with 5-Fu for advanced esophageal cancer. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data and assessed the quality of the included studies. Then meta-analysis was conducted using RevMan 5.1 software. Results A total of 15 RCTs invloving 863 patients were included. The results of meta-analysis suggested that, compared with cisplatin combined with 5-Fu, nedaplatin combined with 5-Fu could improve short-term effects (RR=1.31, 95%CI 1.14 to 1.52, P=0.000 2) and reduce gastrointestinal reaction and renal function impairment, but it was associated with aggravated myelosuppression, increase of thrombocytopenia and leukopenia, and decrease of hemoglobin. There were no significant differences between the two groups in liver function impairment, diarrhea and peripheral neurovirulence. Conclusion Nedaplatin combined with 5-fluorouracil can increase short-term effects and reduce gastrointestinal reaction and renal function impairment. However, nedaplatin is associated with aggravated myelosuppression, so it should be applied in clinic with cautious. Nedaplatin combined with 5-fluorouracil can be used as a replacement chemotherapy regimen for advanced esophageal cancer, but the evidence about long-term effects and safety is still required. For the quality and quantity limitation of the included studies which decreases the level of evidence, so the conclusion of this systematic review only provides some references for clinical practice and research.
ObjectiveTo explore the effect of music therapy on quality of life in patients with gynecologic malignant tumor undergoing chemotherapy. MethodsA hundred patients diagnosed to have gynecologic malignant tumor between January and June 2013 were included in our study. They were divided into intervention group and control group with 50 patients in each. Traditional nursing was given to the patients in the control group, while patients in the intervention group accepted routine and music therapy at the same time. Quality of life questionare C30 scale was used to measure related indexes before and after the intervention. ResultsPhysical function, emotional function, cognitive function, and overall health status for patients in the intervention group changed significantly after the intervention (P<0.05). ConclusionMusic therapy can effectively improve the quality of life in patients with gynecologic malignant tumor undergoing chemotherapy.
