Chemotherapy-induced neutropenia (CIN) is a common hematological adverse events and dose-limiting toxicities of chemotherapy. CIN may lead to dose reduction and delay of chemotherapeutic agents, febrile neutropenia and severe infection, which results in increased treatment cost, reduced efficacy of chemotherapy, and even life-threatening morbidities. Assessment of risk of CIN, early detection of FN and infection, and proper prevention and treatment play a crucial role in reducing the occurrence of CIN-related morbidities, improving patient treatment safety and anticancer efficacy. Based on evidence and expert opinion, the expert committee of Chinese Anti-Cancer Association issued "the consensus on diagnosis and treatment of chemotherapy-induced neutropenia in China (2023 edition)", which is an update version of the 2019 edition, aiming to provide reference for the diagnosis and treatment of CIN for Chinese oncologists.

Oxaliplatin with 5-fluorouracil plus leucovorin (FOLFOX) has become the standard treatment in patients with colorectal cancer. Among known toxicities induced by oxaliplatin, hematological, gastrointestinal and neurological toxicities are common. However, acute pulmonary toxicity associated with oxaliplatin is unusual. One case of interstitial lung disease associated with the FOLFOX protocol is reported here.

BACKGROUND: The objectives of this study were to determine the incidence, outcome and risk factors for HBV reactivation in HBsAg positive breast cancer patients while on anthracycline -based adjuvant chemotherapy. METHDOS: We retrospectively reviewed the records of 2,431 patients with early breast cancer who received adjuvant chemotherapy from March 2001 to December 2005. Among these patients, 111 HBsAg positive women were enrolled in this study. RESULTS: Thirty-seven patients (33.3%) developed acute hepatitis, of which 23 (20.7%) were related to HBV reactivation. Univariate analysis showed that an age > or =47 years (p=0.034) and abnormal sonographic findings such as a fatty liver or cirrhotic changes (p=0.034) were associated with HBV reactivation. However, an HBeAg positive status and the use of corticosteroids were not. Multivariate analysis found that no clinical factors could predict HBV reactivation during chemotherapy. All 23 patients who developed HBV reactivation received lamivudine as a therapeutic measure at the time of HBV reactivation. Despite the use of lamivudine, disruption in the chemotherapy protocol occurred in 18 patients (78.3%) and 14 of these patients had premature termination of their chemotherapy. CONCLUSIONS: HBV reactivation occurred in a significant proportion of HBsAg positive patients during adjuvant anthracycline-based chemotherapy. Once hepatitis developed, most patients could not finish the chemotherapy as planned despite lamivudine treatment. Until the risk factors for reactivation are clearly identified, HbsAg-positive patients should begin prophylactic antiviral treatment before initiating chemotherapy.

BACKGROUND AND OBJECTIVEWhether gemcitabine plus platinum chemotherapy is superior to gemcitabine or platinum single-agent chemotherapy for patients with non-small cell lung cancer (NSCLC) is still in dispute, and the aim of this study is to evaluate the efficacy and safety of gemcitabine combining platinum chemotherapy for patients with NSCLC.

METHODSWe searched relevant randomized controlled trials (RCTs) from VIP, CBM, CNKI, the Cochrane library, PUBMED and EMBASE. We traced the related references and experts in this field and communicated with other authors to obtain the information that has not been found. We made quality assessment of qualified RCTs assessed by the exclusion and inclusion criteria and used RevMan 5.0 provided by the Cochrane Collaboration to perform meta-analysis.

RESULTSFour RCTs were eligible and included 984 patients. Meta analysis results suggested that: compared with gecitabine single-agent chemotherapy, the combination had a statistically significant benefit in increasing the response rate (OR = 3.29, 95% CI: 1.79-6.05, P = 0.000 1) and 2-year survival rate (OR = 3.22, 95% CI: 1.45-7.12, P = 0.004) while increased the risk of the incidence of adverse reactions, especially the grade 3-4 thrombocytopenia (RR = 8.16, 95% CI: 1.71-39.07, P = 0.009); compared with cisplatin single-agent chemotherapy, the combination had a statistically significant benefit in increasing the response rate (OR = 3.51, 95% CI: 2.20-5.60, P < 0.01) and 1-year survival rate (OR = 1.67, 95% CI: 1.16-2.41, P = 0.006) while increased the risk of the incidence of adverse reactions, especially the grade 3-4 thrombocytopenia (OR = 28.55, 95% CI: 14.06-57.04, P < 0.01).

CONCLUSIONCompared with single-agent chemotherapy, the combining can significantly improve the efficiency and survival rate while increase the toxicity rare. The results still need to be proved by high quality RCTs.

The aim of the present study was to determine whether oncologic outcomes and adverse events associated with active on/off intermittent antiandrogen monotherapy (daily bicalutamide, 50 mg per day) are comparable with those of standard external beam radiation therapy (EBRT) or combined androgen blockade (CAB) therapy in prostate cancers with positive surgical margins after radical prostatectomy. Two hundred twenty-three patients with positive surgical margins post-radical prostatectomy who underwent active surveillance (AS, n = 32), EBRT without hormone therapy (n = 55), intermittent antiandrogen monotherapy without EBRT (IAAM, n = 50), or CAB without EBRT (n = 86), between 2007 and 2014, were reviewed retrospectively. Pathologic outcomes, biochemical recurrence rates, radiological disease progression, and adverse events were collected from medical records. Biochemical recurrence rates, biochemical recurrence-free survival rates, and radiological recurrence were not different between the groups (P = 0.225, 0.896, and 0.284, respectively). Adverse event rates and severities were lower for IAAM compared with EBRT or CAB (both P < 0.05), but were comparable to those for AS (P = 0.591 and 0.990, respectively). Grade ≥3 adverse events were not reported in the IAAM or AS groups. Erectile dysfunction and loss of libido rates were lower in the IAAM group compared with the EBRT and CAB groups (P = 0.032). Gastrointestinal complications were more frequently reported in the EBRT group (P = 0.008). Active on/off IAAM treatment might be an appropriate treatment option for patients with positive surgical margins after radical prostatectomy. Furthermore, regarding oncologic outcomes, IAAM was comparable to standard EBRT but had a milder adverse event profile.

OBJECTIVETo observe the efficacy and safety of chemotherapy regimens oxaliplatin combined with capecitabine (CAPOX) or oxaliplatin combined with tegafur, gimeracil and oteracil potassium capsules (S-1)(SOX), and to investigate the value of expression of thymidine phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) proteins in tumor tissue for predicting the efficacy of CAPOX and SOX regimens in advanced gastric cancer patients.

METHODSA total of 107 newly-diagnosed, stage Ⅲc/Ⅳ gastric cancer patients (no surgical indication, ECOG performance scores 0-2 and expected survival time ≥3 months) were recruited with 101 patients evaluated. The patients were randomly divided into two groups. One was study group in which the patients received CAPOX regimen. The other was control group received SOX regimen. Each patient received four cycles, at least two cycles chemotherapy every three weeks and followed up until death or lost. Tumor biopsies were obtained by gastroscopy for immunohistochemical examination of the expression of TP and DPD proteins before chemotherapy. Response rate (ORR), overall survival (OS) and time to tumor progression (TTP) of the patients were assessed.

RESULTSThe objective response rate (ORR) of the study and control groups was 49.0% (5/51) vs. 46.0% (23/50), respectively (P>0.05). The overall survival (OS) was 357.36±24.69 days in the study group and 349.87±22.63 days in the control group, and the time-to-progression (TTP) was 216.75±19.32 days in the study group and 220.54±18.47 days in the control group (P>0.05 for both). Stratified analysis showed that the ORR of TP-positive patients in the study group was significantly higher than that in the control group (72.0 % vs. 41.7 %, P=0.032). There was no significant difference in ORR between the TP-negative patients in the study and control groups (26.9% vs. 50.0%, P=0.087), while the ORR of DPD-positive patients in the control group was significantly higher than that of the study group (51.9% vs. 34.6%, P=0.046). There was no significant difference in the ORR between DPD-negative patients in the study and control groups (64.0% vs. 39.1%, P=0.084). The follow-up showed that the OS (378.42±22.56 days) and TTP (271.77±24.92 days) in the TP-positive patients of the study group were significantly longer than those of the control group (OS: 326.57±19.84 days, and TTP: 229.13±22.68 days)( P<0.05). The OS was 371.25±23.97 days and TTP was 264.66±21.36 days in the DPD-positive patients of control group, significantly longer than those of the study group (OS: 334.73±21.47days, and TTP: 208.58±20.70 days) (P<0.05). But there was no significant difference in the OS and TTP between the TP- and DPD-negative patients in the two groups (P>0.05). In respect of adverse events, both the rates of hematological and non-hematological toxicities were low and similar between the two groups (P>0.05), and well-tolerated by the patients.

CONCLUSIONSBoth CAPOX and SOX regimens are effective chemotherapeutic protocols in treatment of patients with advanced gastric cancer. The expression levels of TP and DPD in tumor tissue can be used as a predictive factor for the efficacy of capecitabine or tegafur, gimeracil and oteracil potassium capsules combined with oxaliplatin regimens. CAPOX chemotherapy regimen is more suitable for the TP-positive gastric cancer patients, and SOX regimen is more suitable for the DPS-positive gastric cancer patients.

BACKGROUND: Patients with transformed chronic myelogenous leukemia(CML) and advanced myelodysplastic syndrome(MDS) have poor prognosis. The aim of this study is to evaluate the feasibility of second chronic phase induction in accelerated phase(CML-AP) or blastic crisis of CML(CML-BC) and remission induction in advanced MDS by combining topoisomerase I inhibitor (topotecan) with topoisomerase II inhibitor(mitoxantrone). METHODS: Twenty-four evaluable patients were entered on this study with a median age of 34 years. Eighteen patients with transformed CML(7 CML-AP, 11 CML-BC) and 6 patients with advanced MDS were treated. Topotecan was administered as 1.5 mg/m2/day by continuous infusion over 24 hours daily for 5 days every 4 to 8 weeks until remission. To enhance the tumoricidal effects, mitoxantrone(12 mg/m2/day, Days 1-3) was added. RESULTS: Eight patients(33+ACU-) achieved a complete remission(CR). Four of 7 patients with CML-AP(57+ACU-), 2 of 4 patients with CML-lymphoid blastic crisis (-LBC)(50+ACU-) and 2 of 6 patients with advanced MDS(33+ACU-) had CR lasting more than 45 days(45 to 400 days). There was no CR in the patients with CML-myeloid blastic crisis(-MBC). The dose level of 1.5 mg/m2/day(7.5 mg/m2/course) of topotecan was well tolerated in all patients. Mucositis occurred in 69+ACU- of patients (severe in 5+ACU-) and diarrhea in 67+ACU-(severe in 8+ACU-). In addition, there were no new or unexpected toxicities in the patients who were treated at this dose(7.5 mg/m2/course). In patients who recovered their neutrophil count, the absolute neutrophil count(ANC) remained below 500/microL for a period of 13 to 58 days(median 21 days) and the time to ANC recovery was associated with pretreatment severity of bone marrow fibrosis(mainly CML patients). Likewise, in the patients who recovered unsupported platelets, the platelets remained below 20,000/microL for a period of 0 to 37 days (median 19 days). CONCLUSION: The combination of topotecan-mitoxantrone has shown modest activity in CML-AP, CML-LBC and advanced MDS with acceptable toxicities.

OBJECTIVES: To determine the effectiveness and toxicity when levamisole was added to the adjuvant combination chemotherapy in patients with operable gastric cancer. METHODS: After en bloc resection of gastric cancer without gross or microscopic evidence of residual disease from April 1991 to December 1992, 100 patients were randomized to 6 months of 5-fluorouracil 1,000 mg/m2/day administered as continuous infusion for 5 days, cisplatin 60 mg/m2/day as intravenous infusion for 1 day with or without levamisole (50 mg every eight hours P.O for a period of three days every 2 weeks for 6 months). This chemotherapy treatment was begun within 2 to 4 weeks after the surgery. The chemotherapy consisted of discrete 5-day courses administered at 4-weeks intervals. All 100 patients are assessable. RESULTS: The fifty patients were assigned to each treatment group. There was no statistical difference and no bias in the distribution of characteristics of the 100 evaluable patients between the two groups. A total of 274 courses of treatment were given in the levamisole group and 260 courses of treatment in non-levamisole group. Eleven patients in each group did not finish planned 6 courses of treatment mainly due to non-compliance. At median follow up of 39 months, 32 patients relapsed 19 in the levamisole group and 13 in the non-levamisole group (p = 0.284). Twenty five patients died of relapsed diseases, 15 in the levamisole group and 10 in the non-levamisole group. The levamisole group tended to show more risk of overall death rate and recurrence than the non-levamisole group. However, this result was not statistically significant at 3 years. The treatment was well tolerated in both treatment groups. The grade 2-3 toxicities were nausea/ vomiting (levamisole, non-levamisole group; 31.7%, 29.3% of treatment courses respectively), diarrhea (7.6%, 8.4%), mucositis (11.6%, 12.3%), and leukopenia (9.8%, 9.6%). CONCLUSION: Levamisole had negative effects on disease-free survival and overall survival when added to adjuvant combination chemotherapy of cisplatin and 5-fluorouracil in patients with operable gastric cancer. Both treatment arms were generally well tolerated and the toxicity profile was similar with or without levamisole.

There has been no standard therapy for patients with metastatic colorectal cancer who have failed to first-line fluorouracil-based treatment. The present study was designed to assess the efficacy and toxicities of a combination of oxaliplatin, 5-fluorouracil (5-FU) and leucovorin in fluoropyrimidine-pretreated patients with metastatic colorectal cancer. Chemotherapy consisted of oxaliplatin 85 mg/m2 on day 1, followed by leucovorin 20 mg/m2 and 5-FU 1,200 mg/m2 on days 1 and 2. Treatment courses were repeated every two weeks. Thirty-nine patients were enrolled in this study. All patients previously received fluoropyrimidine-based chemotherapy. Thirty-one patients were assessable for response and 33 for treatment toxicity. Six patients required dose reduction of 5-FU due to grade III/IV cytopenia. Nausea/vomiting and peripheral neuropathy were common non-hematologic toxicities. Overall response rate was 42.0% including 3 complete response and 10 partial response. The median response duration was 91 days (range, 28-224+). The median duration of progression-free survival was 132 days (range, 40-308). A combination of oxaliplatin, 5-FU, and leucovorin showed high response rate in fluoropyrimidine-pretreated patients with metastatic colorectal cancer, but the duration of response was relatively short. It may be worthwhile to explore its therapeutic potential in the first-line treatment setting.
