RESUMO
BACKGROUND: The addition of immune checkpoint inhibitors to neoadjuvant chemotherapy in operable advanced gastric or gastroesophageal junction (G/GEJ) cancer aroused wide interest. This study was designed to assess the efficacy and safety of neoadjuvant sintilimab, a programmed cell death protein-1 (PD-1) inhibitor, in combination with fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) chemotherapy for HER2-negative locally advanced G/GEJ cancer. METHODS: Eligible patients with clinical stage cT4 and/or cN+M0 G/GEJ cancer were enroled in this phase II study. Patients received neoadjuvant sintilimab (200 mg every 3 weeks) for three cycles plus FLOT (50 mg/m 2 docetaxel, 80 mg/m 2 oxaliplatin, 200 mg/m 2 calcium levofolinate, 2600 mg/m 2 5-fluorouracil every 2 weeks) for four cycles before surgery, followed by four cycles of adjuvant FLOT with same dosages after resection. The primary endpoint was the pathological complete response (pCR) rate. RESULTS: Thirty-two patients were enroled between August 2019 and September 2021, with a median follow-up of 34.8 (95% CI, 32.8-42.9) months. Thirty-two (100%) patients received neoadjuvant therapy, and 29 underwent surgery with an R0 resection rate of 93.1%. The pCR (TRG0) was achieved in 5 (17.2%; 95% CI, 5.8-35.8%) patients, and the major pathological response was 55.2%. Twenty-three (79.3%) patients had T downstaging, 21 (72.4%) had N downstaging, and 19 (65.5%) had overall TNM downstaging. Six (20.7%) patients experienced recurrence. Patients achieving pCR showed better event-free survival (EFS), disease-free survival (DFS), and overall survival (OS) than non-pCR. The estimated 3-year EFS rate, 3-year DFS rate, and 3-year OS rate were 71.4% (95% CI, 57.2-89.2%), 78.8% (95% CI, 65.1-95.5%), and 70.9% (95% CI, 54.8-91.6%), respectively. The objective response rate and disease control rate were 84.4% (95% CI, 68.3-93.1%) and 96.9% (95% CI, 84.3-99.5%), respectively. Twenty-five (86.2%) received adjuvant therapy. The main grade ≥3 treatment-related adverse events (TRAEs) were lymphopenia (34.4%), neutropenia (28.1%), and leukopenia (15.6%). no patients died from TRAE. The LDH level exhibited a better predictive value to pathological responses than PD-L1 and MSI status. CONCLUSIONS: The study demonstrated an encouraging efficacy and manageable safety profile of neoadjuvant sintilimab plus FLOT in HER2-negative locally advanced G/GEJ cancer, which suggested a potential therapeutic option for this population.

PURPOSE: Although the therapy-related bone loss attracts increasing attention nowadays, the differences in chemotherapy-induced bone loss and bone metabolism indexes change among breast cancer (BC) women with different menstrual statuses or chemotherapy regimens are unknown. The aim of the study is to explore the effects of different regimens of chemotherapy on bone health. METHOD: The self-control study enrolled 118 initially diagnosed BC women without distant metastasis who underwent dual-energy X-ray absorptiometry (DXA) bone mineral density (BMD) screening and (or) bone metabolism index monitoring during chemotherapy at Chongqing Breast Cancer Center. Mann-Whitney U test, Cochran's Q test, and Wilcoxon sign rank test were performed. RESULTS: After chemotherapy, the BMD in the lumbar 1-4 and whole lumbar statistically decreased (- 1.8%/per 6 months), leading to a significantly increased proportion of osteoporosis (27.1% vs. 20.5%, P < 0.05), which were mainly seen in the premenopausal group (- 7.0%/per 6 months). Of the chemotherapeutic regimens of EC (epirubicin + cyclophosphamide), TC (docetaxel + cyclophosphamide), TEC (docetaxel + epirubicin + cyclophosphamide), and EC-T(H) [epirubicin + cyclophosphamide-docetaxel and/or trastuzumab], EC regimen had the least adverse impact on BMD, while the EC-TH regimen reduced BMD most (P < 0.05) inspite of the non-statistical difference between EC-T regimen, which was mainly seen in the postmenopausal group. Chemotherapy-induced amenorrhea (estradiol 94 pg/ml vs, 22 pg/ml; FSH 9.33 mIU/ml vs. 61.27 mIU/ml) was proved in premenopausal subgroup (P < 0.001). Except the postmenopausal population with calcium/VitD supplement, the albumin-adjusted calcium increased significantly (2.21 mmol/l vs. 2.33 mmol/l, P < 0.05) after chemotherapy. In postmenopausal group with calcium/VitD supplement, ß-CTX decreased significantly (0.56 ng/ml vs. 0.39 ng/ml, P < 0.05) and BMD were not affected by chemotherapy (P > 0. 05). In premenopausal group with calcium/VitD supplement, PTH decreased significantly (52.90 pg/ml vs. 28.80 pg/ml, P = 0. 008) and hip BMD increased after chemotherapy (0.845 g/m2 vs. 0.952 g/m2, P = 0. 006). As for both postmenopausal and premenopausal group without calcium/VitD supplement, there was a significant decrease in bone mass in hip and lumbar vertebrae after chemotherapy (0.831 g/m2 vs. 0.776 g/m2; 0.895 g/m2 vs. 0.870 g/m2, P < 0.05). CONCLUSION: Chemotherapy might induce lumbar vertebrae BMD loss and spine osteoporosis with regimen differences among Chinese BC patients. Calcium/VitD supplementation could improve bone turnover markers, bone metabolism indicators, and bone mineral density. Early interventions on bone health are needed for BC patients during chemotherapy.

ANTECEDENTES En el marco de la metodología ad hoc para evaluar solicitudes de tecnologías sanitarias, aprobada mediante Resolución de Instituto de Evaluación de Tecnologías en Salud e Investigación N° 111-IETSI-ESSALUD-2021 y ampliada mediante Resolución de Instituto de Evaluación de Tecnologías en Salud e Investigación N° 97-IETSI-ESSALUD2022, se ha elaborado el presente dictamen, el cual expone la evaluación de la eficacia y seguridad de enzalutamida en pacientes adultos con cáncer de próstata resistente a la castración metastásico, con progresión a quimioterapia basada en docetaxel e intolerantes a acetato de abiraterona. Así, el Dr. Nelson Cuevas Muñoz, médico especialista en oncología del Hospital Nacional Edgardo Rebagliati Martins (HNERM), siguiendo la Directiva N° 003-IETSI-ESSALUD-2016, envió a través del comité farmacoterapéutico del Hospital HNERM al Instituto de Evaluación de Tecnologías en Salud e Investigación - IETSI la solicitud de autorización de uso del producto farmacéutico enzalutamida no incluido en el Petitorio Farmacológico de EsSalud. ASPECTOS GENERALES: El cáncer de próstata (CP) es el segundo cáncer más frecuente en hombres a nivel mundial y el más frecuente en Perú; registrándose 30.7 y 44.3 casos nuevos por cada 100 000 hombres en el 2020, respectivamente (GLOBOCAN [Internet] 2022). Asimismo, en el mismo año, se registró más de 375 000 muertes por CP en el mundo y 2433 muertes por CP en el Perú, representando así la segunda causa de muerte por cáncer en la población peruana (GLOBOCAN [Internet] 2022). El tratamiento sistémico de primera línea para el CP en estadios avanzados es la terapia de deprivación de andrógenos (Dawson y Leger 2022). Entre el 10 % y 27 % progresa a esta terapia, y el estado de la enfermedad se conoce como CP resistente a la castración (CPRC) (Bretoni, Ferrario, y Foglia 2019; Colloca et al. 2016). Aproximadamente, más del 70 % de pacientes con CPRC tienen CPRC metastásico (CPRCm) (Bretoni, Ferrario, y Foglia 2019). METODOLOGÍA: Se llevó a cabo una búsqueda bibliográfica exhaustiva con el objetivo de identificar la mejor evidencia sobre la eficacia y seguridad de enzalutamida en pacientes adultos con CPRCm, con progresión a quimioterapia basada en docetaxel e intolerantes a AA. La búsqueda bibliográfica se realizó en las bases de datos PubMed, The Cochrane Library, Web of Science y LILACS. Asimismo, se realizó una búsqueda manual dentro de las páginas web pertenecientes a grupos que realizan evaluación de tecnologías sanitarias (ETS) y guías de práctica clínica (GPC) incluyendo el National Institute for Health and Care Excellence (NICE), la Canadian Agency for Drugs and Technologies in Health (CADTH), el Scottish Medicines Consortium (SMC), el Scottish Intercollegiate Guidelines Network (SIGN). el Institute for Quality and Efficiency in Healthcare (IQWiG por sus siglas en alemán), la International Database of GRADE Guideline, el Centro Nacional de Excelencia Tecnológica en Salud (CENETEC), la Guidelines International Network (GIN), el National Health and Medical Research Council (NHMRC), la Cancer Guidelines Database, el New Zealand Guidelines Group (NZGG), el Instituto de Evaluación Tecnológica en Salud (IETS), el Instituto de Efectividad Clínica y Sanitaria (IECS), la Base Regional de Informes de Evaluación de Tecnologías en Salud de las Américas (BRISA), la Organización Mundial de la Salud, el Ministerio de Salud del Perú (MINSA) y el Instituto de Evaluación de Tecnologías en Salud e Investigación (IETSI). Además, se realizó una búsqueda de GPC de las principales sociedades o instituciones especializadas en oncología o urología, tales como: National Comprehensive Cancer Network (NCCN), la Cancer Council Australia (CCA), la European Society for Medical Oncology (ESMO), la American Society of Clinical Oncology (ASCO), la Sociedad Española de Oncología Médica (SEOM), la European Association of Urology (EAU) y la American Urological Association (AUA). Finalmente, se realizó una búsqueda en la página web de registro de ensayos clínicos (EC) www.clinicaltrials.gov, para identificar EC en curso o que no hayan sido publicados aún. RESULTADOS: Luego de la búsqueda bibliográfica hasta mayo de 2023, se identificaron cinco GPC elaboradas por la NCCN (NCCN 2022), la ESMO (Parker et al. 2020), la EAU (EAU 2022a), la SEOM (González del Alba et al. 2021) y la ASCO (Basch et al. 2014), y un ECA denominados AFFIRM (Scher et al. 2012). CONCLUSIÓN: Por lo expuesto, el Instituto de Evaluación de Tecnologías en Salud e Investigación aprueba el uso de enzalutamida para pacientes adultos con CPRCm, con progresión a quimioterapia basada en docetaxel, con contraindicaciones al uso, o desarrollo de reacciones adversas que lleven a la interrupción, de AA, como producto farmacéutico no incluido en el Petitorio Farmacológico de EsSalud, según lo establecido en el Anexo N° 1. La vigencia del presente dictamen preliminar es de un año a partir de la fecha de publicación. Así, la continuación de dicha aprobación estará sujeta a la evaluación de los resultados obtenidos y de mayor evidencia que pueda surgir en el tiempo.

BACKGROUND: Oral mucositis (OM) is an unpleasant adverse event in patients receiving chemotherapy. A prospective feasibility study showed that elemental diet (ED), an oral supplement that does not require digestion, may prevent OM. Based on this, we established a central review system for oral cavity assessment by dental oncology specialists blinded to background data. We used this system to elucidate the preventive effect of an ED against OM in patients with esophageal cancer receiving docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy. PATIENTS AND METHODS: In this phase III, multicenter, parallel-group, controlled trial, patients consuming a normal diet orally were randomly assigned (1 : 1) to receive two cycles of DCF with (group A) or without (group B) an ED (Elental® 160 g/day). We assessed the incidence of grade ≥2 OM evaluated by two reviewers, changes in body weight, prealbumin, C-reactive protein, and DCF completion rate based on ED compliance. RESULTS: Of the 117 patients randomly assigned to treatment, four failed to start treatment and were excluded from the primary analysis; thus, groups A and B comprised 55 and 58 patients, respectively. There were no significant differences in background characteristics. Grade ≥2 OM was observed in eight (15%) and 20 (34%) patients in groups A and B, respectively (P = 0.0141). Changes in body weight and prealbumin during the two DCF cycles were significantly higher in group A than B (P = 0.0022 and 0.0203, respectively). During the first cycle, changes in C-reactive protein were significantly lower in group A than B (P = 0.0338). In group A (receiving ED), the DCF completion rate was 100% in patients with 100% ED compliance and 70% in patients failing ED completion (P = 0.0046). CONCLUSIONS: The study findings demonstrate that an ED can prevent OM in patients with esophageal cancer receiving chemotherapy.

INTRODUCTION: The effects of chemotherapy are known to depend on the time of administration. Circadian rhythms are disturbed in tumors and in tumor bearers. Agents involved in controlling the circadian rhythms (chronobiotics) potentially can modify the outcomes of chemotherapeutics administered at different times of the day. Pineal hormone melatonin (MT) is a prototypic chronobiotic. OBJECTIVE: The aim of the study was to investigate if MT can affect efficacy or toxicity of chemotherapy drugs administered at the extreme time points of the working day of hospital personnel. METHODS: Cyclophosphamide, adriamycin, and 5-fluorouracil (CAF) and adriamycin and docetaxel (AT) cytotoxic drug combinations were administered on day 0 at 11:00 a.m. or at 5:00 p.m. (UTC+03:00) to 6-month-old female HER2/neu transgenic FVB/N mice bearing mammary adenocarcinomas. Some mice were additionally provided with MT in drinking water (20 mg/L) at night 1 week before or 3 weeks after treatment or during both periods. Tumor node sizes, body weight, and blood cell counts were determined right before treatment and on days 2, 7, 14, and 21. RESULTS: Significant decrease in the mean tumor node volume was found by days 14 and 21 upon all CAF and AT treatment schedules, except in animals treated with AT at 5:00 p.m. without supplementation with MT. In the latter case, mean tumor node volume on day 21 was the same as in the control. Supplementation of AT administered at 5:00 p.m. with MT improved the tumor response. CAF and AT regimens supplemented with MT also augmented the number of tumor nodes that did not increase by more than 20% by day 21 as compared to CAF or AT alone, respectively. This effect was significant in groups treated with AT at 5:00 p.m. and consistent upon other schedules. On day 7, leukopenia and anemia were registered in groups treated with CAF regimen; however, blood cell counts normalized by day 14. Both CAF and AT were associated with drop in the body weight registered on day 7. Supplementation with MT did not affect changes of the body weight and blood counts. CONCLUSIONS: MT supplementation to cytotoxic drugs can improve antitumor response, especially if it is blunted because of an inappropriate time of administration.

Introduction: Myelosuppresion is a common side effect of chemotherapy and granulocyte-colony stimulating factor (G-CSF) is often used to reduce the risk of neutropenic events. The purpose of this exploratory analysis was to investigate neutropenic complications in the phase III PANTHER trial of standard 3-weekly chemotherapy with 5-fluorouracil, epirubicin and cyclophosphamide plus docetaxel (FEC/D) versus bi-weekly tailored dose-dense EC/D adjuvant chemotherapy in breast cancer.Patients and methods: Febrile neutropenia, neutropenic infection and infection grade 3-4 according to CTC AE 3.0, were explored in relation to G-CSF use. Per cycle analysis was performed concerning dose reduction and dose delays in conjunction with G-CSF administration.Results: In the experimental group, 98.9% of patients received primary G-CSF support during EC and 97.4% during docetaxel, compared with 49.7% during FEC and 63.88% during docetaxel in the standard group. Overall, the use of G-CSF was associated with a lower risk for developing neutropenic events (OR 0.44, 95% CI 0.35-0.55, p < .001). Chemotherapy delays due to neutropenia and leukopenia were significantly decreased among patients that received G-CSF (OR 0.098, 95% CI 0.06-0.15 and OR 0.32, 95% CI 0.18-0.58, respectively).Discussion: In conclusion, G-CSF support reduces neutropenic events and permits increased relative dose intensity, which is essential for improved survival outcomes.

Importance: Prospective assessment of treatments known to benefit patients in global clinical trials in specific racial groups is essential. Objective: To compare the efficacy, safety, and tolerability of adding pertuzumab to trastuzumab and docetaxel vs placebo, trastuzumab, and docetaxel in Asian patients with ERBB2-positive early or locally advanced breast cancer. Design, Setting, and Participants: This multicenter, double-blind, placebo-controlled phase 3 trial enrolled 329 women with ERBB2-positive early (T2-3, N0-1, M0) or locally advanced breast cancer (T2-3, N2 or N3, M0; T4, any N, M0) and primary tumor larger than 2 cm from March 14, 2016, to March 13, 2017. Analysis of the primary end point was performed on an intention-to-treat basis. Interventions: Before surgery, patients received 4 cycles of intravenous pertuzumab (840-mg loading dose and 420-mg maintenance doses), trastuzumab (8-mg/kg loading dose and 6-mg/kg maintenance doses), and docetaxel (75 mg/m2) or intravenous placebo, trastuzumab, and docetaxel every 3 weeks. After surgery, patients received 3 cycles of intravenous fluorouracil, epirubicin, and cyclophosphamide followed by 13 cycles of the same intravenous anti-ERBB2 therapy (pertuzumab and trastuzumab or placebo and trastuzumab) for up to 1 year. Main Outcomes and Measures: The primary end point was independent review committee-assessed total pathologic complete response rate. The 2-sided Cochran-Mantel-Haenszel test, stratified by disease category and hormone receptor status, was used to compare rates between treatment groups. Results: In total, 329 female patients were randomized (pertuzumab, 219; and placebo, 110; mean [SD] age, 48.8 [9.5] years). In the intention-to-treat population, total pathologic complete response rates were 39.3% (86 of 219) in the pertuzumab group and 21.8% (24 of 110) in the placebo group (difference, 17.5% [95% CI, 6.9%-28.0%]; P = .001). Of the most common grade 3 or higher adverse events, there was a higher incidence of neutropenia in the pertuzumab group (83 of 218 [38.1%] vs 36 of 110 [32.7%]). Serious adverse events were reported in 10.1% of patients (22 of 218) in the pertuzumab group and 8.2% of patients (9 of 110) in the placebo group. Conclusions and Relevance: Treatment with pertuzumab, trastuzumab, and docetaxel resulted in a statistically significant improvement in the total pathologic complete response rate vs placebo, trastuzumab, and docetaxel for the neoadjuvant treatment of ERBB2-positive early or locally advanced breast cancer in Asian patients. Safety data were in line with the known pertuzumab safety profile and generally comparable between treatment groups. The PEONY trial adds to the totality of data showing the benefit of the pertuzumab regimen. Trial Registration: ClinicalTrials.gov identifier: NCT02586025.

OBJECTIVE: This meta-analysis was performed to assess the efficacy of cryotherapy and nail solution (NS) use in preventing nail toxicity (NT) induced by taxane-based chemotherapy. METHODS: PubMed, EMBASE, Cochrane Library and ClinicalTrials.gov registry databases were searched for relevant studies published up to December 2018. The primary outcome was taxane-induced NT. Secondary outcomes were skin toxicity (ST), time to toxicity and patient comfort. RESULTS: We reviewed three randomised control trials and six prospective studies with 708 patients. For meta-analysis, taxane-induced NT grading was compared. NT and ST were significantly lower in the cryotherapy patients than in the controls (grade 1 NT: risk ratio [RR] = 0.51, 95% confidence interval [CI] = 0.30-0.89; grade 2-3 NT: RR = 0.36, 95% CI = 0.11-1.12; total NT: RR = 0.49; 95% CI = 0.30-0.79; ST: RR = 0.46, 95% CI = 0.33-0.64). The NS-treated patients exhibited significantly lower NT than the controls. CONCLUSIONS: Nail solution-treated or cryotherapy patients exhibited lower NT incidence and severity associated with taxane-based chemotherapy than the controls. For patients who can afford and comply with NS use or cryotherapy, these measures represent effective prophylactic management for taxane-induced NT and improve their quality of life and functional statuses. Further studies are needed to establish the routine usage protocols, long-term efficacy and safety for these interventions.

Docetaxel (DTX) has been used in cancer treatments for several decades, but it results in many adverse apoptotic effects through excessive production of reactive oxygen species (ROS) in some tissue including the kidney and testes. We aimed to investigate potential modulatory roles of melatonin (MEL) and selenium (Se) against DTX-induced apoptosis and oxidative injury in the testes and kidney of mice. Thirty-two mice were divided into four equal groups as control, DTX, DTX + MEL and DTX + Se. DTX group was treated with a single intraperitoneal dose of DTX. After DTX treatment, MEL and Se were administered to the mice in the DTX + MEL and DTX + Se groups for 7 days respectively. Increased lipid peroxidation, ROS, apoptosis, caspase-3 and caspase-9 activities in the kidney and testes of the DTX group were diminished by treatment with MEL and Se. DTX-induced decreases in vitamin E (α- and γ-tocopherol), glutathione peroxidase and reduced glutathione levels in the kidney and testis were increased following MEL and Se treatments. In conclusion, our data show that MEL and Se can act as modulators against DTX-induced apoptosis and oxidative damage in the kidney and testis through up-regulation of glutathione and vitamin E and down-regulation of caspase pathways.

AIM: We aimed to retrospectively investigate the outcomes and pathological effects of retrograde superselective intra-arterial chemoradiotherapy (IACRT) combined with hyperthermia on metastatic lymph nodes of patients with oral squamous cell carcinoma. PATIENTS AND METHODS: Patients with lymph node metastasis from oral cancer were treated with IACRT using cisplatin plus docetaxel combined with hyperthermia prior to surgical removal 8 weeks after completion of IACRT and hyperthermia. The locoregional control and overall survival rates were calculated using the Kaplan-Meier method. RESULTS: A total of 35 patients received the combination therapy of whom 26 received it as definitive treatment and in the rest, it was administered as preoperative treatment. The 5-year locoregional control and overall survivaI rates were 95.6% and 80.2% in the definitive-treatment group, and 100% and 66.6% in the preoperative-treatment group, respectively. CONCLUSION: The combination therapy provided good outcomes in patients with lymph node metastases from advanced oral cancer.

BACKGROUND: In treatment of locally advanced squamous cell carcinoma of the head and neck (SCCHN), the use of docetaxel, cisplatin, and 5-fluorouracil (TPF) followed by high-dose cisplatin chemoradiotherapy (CRT) carries concerns over toxicity. We evaluated the feasibility of TPF as induction chemotherapy (IC) to Japanese patients and the tolerability of CRT with fractionated administration of cisplatin after IC. METHODS: Patients with unresectable stage III, IV SCCHN received IC followed by CRT. IC consisted of three 3-week cycles of docetaxel 70-75 mg/m2 on day 1, cisplatin 70-75 mg/m2 on day 1, and 5-fluorouracil 750 mg/m2 on days 1-5. Patients subsequently received IMRT concomitant with fractionated administration of cisplatin (20 mg/m2) on days 1-4, repeated every 3 weeks. The primary endpoint was completion of the three cycles of IC. RESULTS: Forty-eight patients were enrolled. The IC treatment completion rate was 85%. Grade 3-4 toxicities of TPF were neutropenia (79%) and febrile neutropenia (15%). Thirty-eight patients (79%) achieved a response after IC. Forty patients subsequently underwent CRT. Thirty-three patients (83%) completed the planned cycles of fractionated administration of cisplatin, but seven (18%) did not. Grade 3-4 toxicities during CRT were neutropenia (23%), mucositis (53%), and dysphagia (33%). With a median follow-up of 36.1 months, 3-year overall survival was 65%. CONCLUSION: TPF IC is feasible and CRT with fractionated administration of cisplatin after IC is tolerable. IC followed by CRT appears to be a useful and safe sequential treatment.

BACKGROUND: Anthracyclines and taxanes are chemotherapeutic agents widely used in a sequential regimen in the adjuvant and neoadjuvant treatment of early breast cancer to reduce the risk of cancer recurrence. Standard practice is to administer anthracycline-based chemotherapy followed by a taxane. Anthracyclines tend to be administered first as they were established before taxanes for treatment of early breast cancer. OBJECTIVES: To assess whether the sequence in which anthracyclines and taxanes are administered affects outcomes for people with early breast cancer receiving adjuvant or neoadjuvant therapy. SEARCH METHODS: We searched Cochrane Breast Cancer's Specialised Register, CENTRAL, MEDLINE, Embase, the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP) and ClinicalTrials.gov on 1 February 2018. SELECTION CRITERIA: Randomised controlled trials comparing administering a taxane prior to an anthracycline with taxane following anthracycline to people with early breast cancer receiving chemotherapy. The studies needed to have reported on at least one of our outcomes of interest, which included overall survival, disease-free survival, pathological response, treatment adherence, toxicity and quality of life. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data, assessed risk of bias and quality of the evidence. The primary outcome measure was overall survival. Secondary outcomes included disease-free survival, pathological response (in the neoadjuvant setting only), adverse events, treatment adherence and quality of life. For time-to-event outcomes of overall survival and disease-free survival, we derived hazard ratios (HRs) with 95% confidence intervals (CI) where possible. For dichotomous outcomes of pathological complete response, treatment adherence and adverse events, we reported the treatment effect as a risk ratio (RR) with 95% CI where possible. We used GRADE to assess the certainty of the evidence separately for the neoadjuvant and adjuvant settings. MAIN RESULTS: There were 1415 participants in five neoadjuvant studies and 280 participants in four adjuvant studies involving five treatment comparisons. Four of the five neoadjuvant studies collected data for the primary outcome (overall survival) and two studies had data available; one of the four adjuvant studies collected overall survival data.The neoadjuvant studies suggested that the administration of taxanes first probably resulted in little to no difference in overall survival (HR 0.80, 95% CI 0.60 to 1.08; 947 participants; 2 studies; moderate-certainty evidence) and disease-free survival (HR 0.84, 95% CI 0.65 to 1.09; 828 participants; 1 study; moderate-certainty evidence). Administration of taxanes first also resulted in little to no difference in pathological complete response (absence of cancer in the breast and axilla: RR 1.15, 95% CI 0.96 to 1.38; 1280 participants; 4 studies; high-certainty evidence). However, there appeared to be a trend in favour of taxanes first. Studies reported treatment adherence using a range of measures. Administration of taxanes first probably did not increase the likelihood of requiring dose reductions compared to administration of anthracyclines first (RR 0.81, 95% CI 0.59 to 1.11; 280 participants; 1 study; moderate-certainty evidence). There was probably little to no difference in the risk of grade 3/4 neutropenia (RR 1.25, 95% CI 0.86 to 1.82; 280 participants, 1 study; moderate-certainty evidence) or grade 3/4 neurotoxicity (RR 0.95, 95% CI 0.55 to 1.65; 1108 participants; 2 studies; low-certainty evidence) when taxanes were given first. There were no data on quality of life.Only one adjuvant study collected data on overall survival and disease-free survival but did not report data. Administration of taxanes first reduced the risk of grade 3/4 neutropenia (RR 0.62, 95% CI 0.40 to 0.97; 279 participants; 4 studies, 5 treatment comparisons; high-certainty evidence) and appeared to result in little to no difference in grade 3/4 neurotoxicity (RR 0.78, 95% CI 0.25 to 2.46; 162 participants; 3 studies; low-certainty evidence). There was probably little to no difference in the proportions experiencing dose delays when taxanes are given first compared to anthracyclines given first (RR 0.76, 95% CI 0.52 to 1.12; 238 participants; 3 studies, 4 treatment comparisons; moderate-certainty evidence). One study reported on quality of life and indicated that scores (using the Functional Assessment of Cancer Therapy - Breast Cancer (FACT-B) validated questionnaire) were similar in both groups though did not provide numerical data. AUTHORS' CONCLUSIONS: In the neoadjuvant setting, there is high- to low-certainty evidence of equivalent outcomes for the sequence in which taxanes are delivered. In the adjuvant setting, none of the studies reported on overall survival or disease-free survival. In most institutions, standard practice would be to deliver anthracycline followed by taxane, and currently available data do not support a change in this practice. We wait for the full-text publication of a relevant neoadjuvant study for women with HER2-negative breast cancer for inclusion in an update of this review.

Clinical trial data forms the foundation of how we treat men with metastatic prostate cancer who are initiating therapy. However, clinical trial data does not answer everything; hence, good clinical practice, pragmatism, and occasionally extrapolation drives how we manage these patients. Fortunately, multiple international guideline committees meet regularly and offer clinical guidance. In this mini-review, we focus on the United States National Comprehensive Cancer Network, European Society for Medical Oncology, and European Association of Urology (EAU) recommendations for the initial treatment of metastatic prostate cancer.

BACKGROUND: In addition to established prognostic factors, individual lifestyle-associated factors, such as obesity, physical activity, and diet, seem to modulate the course of breast cancer. The aim of this analysis was to evaluate the influence of weight changes during adjuvant chemotherapy on outcome in a large multicenter prospectively randomized trial. PATIENTS AND METHODS: The ADEBAR trial compares a sequential chemotherapy consisting of epirubicin/cyclophosphamide followed by docetaxel to an epirubicin/5-fluorouracil/cyclophosphamide regimen in patients with lymph node-positive early breast cancer. Body weight was measured before each cycle of chemotherapy. According to the relative weight change (≥ 5%) between the first and the last cycle, patients were categorized into the weight gain, weight loss, or stable weight group. Overall survival (OS) and disease-free survival were assessed by univariate Kaplan-Meier and multivariate Cox regression analyses. RESULTS: Concise data from 1080 of 1493 participants who completed all cycles of chemotherapy were available for analysis. Of 307 patients (24.8%) whose weight changed by ≥ 5%, 120 patients (11.1%) lost and 187 (17.3%) gained weight. Multivariate analysis showed a significant independent effect of weight change on OS (P = .039), but not on disease-free survival (P = .111). Both weight change groups had a worse OS compared to patients with stable weight (weight gain: hazard ratio, 1.55; 95% confidence interval, 1.01-2.40; P = .047; weight loss: hazard ratio, 1.55; 95% CI, 0.97-2.47; P = .067). CONCLUSION: Weight change of > 5% during adjuvant chemotherapy in patients with high-risk early breast cancer is associated with poor OS.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and disabling side effect of taxanes. Acetyl-L-carnitine (ALC) was unexpectedly found to increase CIPN in a randomized trial. We investigated the long-term patterns of CIPN among patients in this trial. Methods: S0715 was a randomized, double-blind, multicenter trial comparing ALC (1000 mg three times a day) with placebo for 24 weeks in women undergoing adjuvant taxane-based chemotherapy for breast cancer. CIPN was measured by the 11-item neurotoxicity (NTX) component of the FACT-Taxane scale at weeks 12, 24, 36, 52, and 104. We examined NTX scores over two years using linear mixed models for longitudinal data. Individual time points were examined using linear regression. Regression analyses included stratification factors and the baseline score as covariates. All statistical tests were two-sided. Results: Four-hundred nine subjects were eligible for evaluation. Patients receiving ALC had a statistically significantly (P = .01) greater reduction in NTX scores (worse CIPN) of -1.39 points (95% confidence interval [CI] = -2.48 to -0.30) than the placebo group. These differences were particularly evident at weeks 24 (-1.68, 95% CI = -3.02 to -0.33), 36 (-1.37, 95% CI = -2.69 to -0.04), and 52 (-1.83, 95% CI = -3.35 to -0.32). At 104 weeks, 39.5% on the ALC arm and 34.4% on the placebo arm reported a five-point (10%) decrease from baseline. For both treatment groups, 104-week NTX scores were statistically significantly different compared with baseline (P < .001). Conclusions: For both groups, NTX scores were reduced from baseline and remained persistently low. Twenty-four weeks of ALC therapy resulted in statistically significantly worse CIPN over two years. Understanding the mechanism of this persistent effect may inform prevention and treatment strategies. Until then, the potential efficacy and harms of commonly used supplements should be rigorously studied.

Purpose This phase III study compared SB3, a trastuzumab (TRZ) biosimilar, with reference TRZ in patients with human epidermal growth factor receptor 2-positive early breast cancer in the neoadjuvant setting ( ClinicalTrials.gov identifier: NCT02149524). Patients and Methods Patients were randomly assigned to receive neoadjuvant SB3 or TRZ for eight cycles concurrently with chemotherapy (four cycles of docetaxel followed by four cycles of fluorouracil, epirubicin, and cyclophosphamide) followed by surgery, and then 10 cycles of adjuvant SB3 or TRZ. The primary objective was comparison of breast pathologic complete response (bpCR) rate in the per-protocol set; equivalence was declared if the 95% CI of the ratio was within 0.785 to 1.546 or the 95% CI of the difference was within ± 13%. Secondary end points included comparisons of total pathologic complete response rate, overall response rate, event-free survival, overall survival, safety, pharmacokinetics, and immunogenicity. Results Eight hundred patients were included in the per-protocol set (SB3, n = 402; TRZ, n = 398). The bpCR rates were 51.7% and 42.0% with SB3 and TRZ, respectively. The adjusted ratio of bpCR was 1.259 (95% CI, 1.085 to 1.460), which was within the predefined equivalence margins. The adjusted difference was 10.70% (95% CI, 4.13% to 17.26%), with the lower limit contained within and the upper limit outside the equivalence margin. The total pathologic complete response rates were 45.8% and 35.8% and the overall response rates were 96.3% and 91.2% with SB3 and TRZ, respectively. Overall, 96.6% and 95.2% of patients experienced one or more adverse event, 10.5% and 10.7% had a serious adverse event, and 0.7% and 0.0% had antidrug antibodies (up to cycle 9) with SB3 and TRZ, respectively. Conclusion Equivalence for efficacy was demonstrated between SB3 and TRZ on the basis of the ratio of bpCR rates. Safety and immunogenicity were comparable.

PURPOSE: Chemotherapy-induced peripheral neuropathy (CIPN) limits the dose of chemotherapy and reduces patients' quality of life. Goshajinkigan is a Japanese herbal medicine used to alleviate neuropathy and general pain. A clinical guideline for prevention and management of CIPN stated that the prophylactic efficacy of goshajinkigan against CIPN was inconclusive. We conducted a systematic review to examine whether goshajinkigan prevents CIPN in patients receiving neurotoxic chemotherapy. METHODS: We searched PubMed, EMBASE, Ichushi, and the Cochrane Central Register of Controlled Trials for eligible trials. Randomized controlled trials that examined the efficacy and safety of goshajinkigan for prevention of CIPN were included. Our primary outcomes were incidence of CIPN, response to chemotherapy, and adverse effects. We pooled data using a random effects model. RESULTS: We analyzed five trials involving a total of 397 patients. When evaluated with Neurotoxicity Criteria of Debiopharm, goshajinkigan was associated with reduced incidence of CIPN of grade ≥ 1 (risk ratio [RR] 0.43; 95% CI, 0.27 to 0.66) and grade 3 (RR 0.42; 95% CI, 0.25 to 0.71), but this beneficial association was not found for grade ≥ 2 of CIPN. Goshajinkigan was not associated with reduced incidence of CIPN when assessed with the National Cancer Institute Common Terminology Criteria for Adverse Events, or improved response to chemotherapy. Goshajinkigan was well tolerated based on one trial. CONCLUSIONS: Goshajinkigan is unlikely to prevent CIPN in patients undergoing neurotoxic chemotherapy. Given the low quality and insufficient amount of the evidence, use of goshajinkigan as standard of care is not currently recommended.
