RESUMO

Invasive fungal infections (IFIs) are a significant cause of morbidity and mortality in de-novo acute myeloid leukemia patients receiving induction chemotherapy. Despite using posaconazole, a broad-spectrum antifungal, for IFI prophylaxis, the breakthrough IFI rate is high in the real-world setting. One of the reasons could be frequent suboptimal plasma posaconazole levels. In the present study, we evaluated if therapeutic drug monitoring (TDM) guided posaconazole prophylaxis can reduce the IFI rates in comparison to a historical cohort. We enrolled 90 patients, > / = 16 years of age, without baseline IFIs, planned for remission induction therapy. All patients were started on posaconazole suspension 200 mg TDS and the dose was increased in a stepwise manner if trough levels were found to be suboptimal (< 350 ng/ml for day 2 or < 700 ng/ml subsequently). The TDM based approach resulted in a significant decline in breakthrough IFI rates (18% versus 52%, P < 0.0001) A total of 69 patients (78%) required dose escalation. Thirty-one patients required change in antifungals due to either suboptimal levels, persistent fever, diarrhoea or vomiting. We could not demonstrate an exposure-response relationship but the difference in IFI rates in patients with a median posaconazole level > / = 700 ng/ml (0%) and < 700 ng/ml (21.6%) was clinically meaningful. Posaconazole levels were found to be significantly lower in patients on antacids and prokinetics. The incidence of posaconazole-related grade 3 toxicity was low (2.3%). Thus TDM-based dosing of posaconazole helps reduce breakthrough IFI rate and should be a part of posaconazole prophylaxis.

RESUMO

PURPOSE: The POP-RT phase III randomized trial showed improved biochemical failure-free survival and metastasis-free survival with whole pelvic radiotherapy (WPRT) versus prostate-only radiotherapy (PORT) for high/very high-risk prostate cancer, albeit with worse RTOG late urinary toxicity. We report updated late urinary adverse effects and bladder dose-effect relations within this trial. MATERIALS/METHODS: Late urinary toxicity, and cumulative severity of each symptom over the follow-up period was graded using CTCAE v5.0. Bladder dosimetry in 5-Gy increments (V5, V10, V15...V65Gy, V68Gy) in the approved radiotherapy plans was compared for urinary symptoms and overall grade 2+ toxicity. Potential factors influencing urinary toxicity were tested using multivariable logistic regression analysis. Updated urinary quality of life (QOL) scores were compared between the trial arms. RESULTS: Complete combined data for late urinary symptoms and dosimetry was available for 193/224 patients. At a median follow-up of 75 months, cumulative late urinary CTCAE grade 3 toxicity was low and similar for WPRT and PORT (5.2% vs 4.1%, p=0.49), while grade 2 toxicity was 31.3% vs 22.7% respectively (p=0.12). Cumulative rates of each urinary symptom were similar between both arms. Multivariable analysis with age at diagnosis, known diabetes, tumor stage, trial arm, prior TURP, grade 2+ acute urinary toxicity, low bladder dose (V10Gy) and moderate bladder dose (V40Gy) did not identify any significant association with late urinary toxicity. Urinary QOL scores was similar between both the arms for all the symptoms. CONCLUSION: Over long term follow up, whole pelvic radiotherapy resulted in low (∼5%) and similar grade 3 cumulative urinary toxicity as prostate-only radiotherapy. The long term patient-reported QOL scores were similar. No causative factors affecting the late urinary toxicity were identified.

RESUMO

INTRODUCTION: CDKN2A/B homozygous deletion is one of the defining features of grade 4 in IDH-mutant astrocytic tumours. AIM: To evaluate CDKN2A/B-deletion in IDH-mutant astrocytic tumours and its clinicopathological impact. MATERIALS AND METHODS: CDKN2A/B-deletion was evaluated by Fluorescence in-situ hybridisation (FISH) and interpreted by two recently accepted methods. RESULTS: Eighty-three out of 94 cases (histologically-grade 2: 3, grade 3: 46, grade 4: 34) were interpretable on FISH. Concordant CDKN2A/B-deletion was observed in 71% (27/38) of lower-grade tumours (n = 49) and 90% (27/30) of histological grade 4 tumours (n = 34). Both the interpretation methods showed good agreement (Kappa = 0.75). CDKN2A/B-deletion showed an inverse correlation for < 10% MIB-1 labeling index (p = 0.01) while that by method-2 showed a significant correlation for grade 4 (p = 0.02). No significant correlation was observed for any other clinicopathological parameters. Twenty-four patients showed progression/recurrence (including deaths), and no significant difference in frequency of CDKN2A/B deletion was observed among cases with disease progression across different histological grades. CONCLUSIONS: CDKN2A/B-deletion was observed across all the histological grades of IDH-mutant astrocytic tumours, expectedly more in the higher grade. FISH, as a method, can be used for the detection of CDKN2A/B homozygous deletion, when there is concordant interpretation.

RESUMO

Various reduced-intensity conditioning (RIC) regimens are used to decrease toxicity while providing comparable outcomes to myeloablative regimens. We compared toxicity and outcomes between two RIC regimens, fludarabine with melphalan (Flu-Mel) and fludarabine with treosulfan (Flu-Treo), retrospectively over a 10-year period in two donor groups, matched related donor (MRD)/matched unrelated donor (MUD) and haploidentical (Haplo) transplants. The study included 138 patients, of which 105 received MRD/MUD (Flu-Mel: 94, Flu-Treo: 11) and 33 Haplo (Flu-Mel: 17, Flu-Treo: 16) transplants. In the MRD/MUD group, 44 (47%) of patients who received Flu-Mel had grade 3/4 oral mucositis compared to 1 (9%) who received Flu-Treo (P = 0.02). Corresponding numbers in the Haplo group were 7 (41%) and 1 (6%). Grade 3/4 diarrhoea was more frequent with Flu-Mel than Flu-Treo in the Haplo group (41% vs 6%; P = 0.039), but not the MRD/MUD group. Median follow-up time for all patients was 4.8 years. Five-year OS in the MRD/MUD group was 62% with Flu-Mel versus 53% with Flu-Treo (P = 0.0694). Similarly, 5-year OS was 41% with Flu-Mel and 28% with Flu-Treo (P = 0.770) in the Haplo group. Severe mucositis and diarrhoea were significantly less frequent with Flu-Treo than Flu-Mel. Flu-Treo provided comparable outcomes to Flu-Mel in all donor transplants.

RESUMO

PURPOSE: Human epidermal growth factor receptor 2 (HER2) overexpression is seen in 4%-16% of biliary tract cancers (BTCs). We aimed to evaluate the clinical activity of gemcitabine-cisplatin (GC) plus anti-HER2 antibody trastuzumab as initial treatment in HER2-positive BTCs. METHODS: This study was an investigator-initiated, open-label, single-arm, multi-institutional, phase II trial in adult patients with HER2-positive (defined as immunohistochemistry [IHC] 3+ or IHC 2+ and fluorescent in situ hybridization-positive), treatment-naïve BTCs. The primary end point of the study was 6-month progression-free survival (PFS). Next-generation sequencing was performed on tissue samples to evaluate mutational status. RESULTS: From March 2020 to August 2022, of the 876 screened patients, 118 (13.4%) were found to have HER2-positive status, of whom 90 were enrolled in the study. Most patients had GBC (n = 96; 96%) with two or more sites of metastatic disease (n = 70; 78%). With a median follow-up of 17.3 (95% CI, 15.22 to 19.32) months, 72 patients had disease progression with a median PFS of 7 (95% CI, 6.2 to 7.8) months. The diagnosis to event 6-month PFS rate was 75.6% (95% CI, 66.6 to 84.6). A complete or partial response was seen in 50 (55.5%) patients and 22 (24.4%) patients had stable disease as the best response to treatment, for an overall disease control rate of 80%. The presence of isolated TP53 mutations was associated with inferior PFS compared with other mutations (TERT promoter, HER2, PIK3CA, etc) or no detected mutations (6.51 v 12.02 v 10.58 months; P < .001). CONCLUSION: The combination of GC and trastuzumab achieved its primary end point of improving PFS compared with historical data in the treatment-naïve HER2-positive BTC. Evaluating additional mutations such as TP53 and PIK3CA along with HER2 testing may help to preferentially select patients for anti-HER2 therapy in the future (Clinical Trial Registry India number: CTRI/2019/11/021955).

RESUMO

PURPOSE: The objective of this study was to compare clinical outcomes of intensity-modulated radiation therapy (IMRT) alone versus IMRT + brachytherapy (BT) in patients with T1-T2N0M0 oropharyngeal squamous cell cancers (OPSCC). METHODS AND MATERIALS: This open-label randomized controlled trial was conducted at Tata Memorial Hospital, Mumbai, India. Patients with stage I and II OPSCC were considered for IMRT to a dose of 50 Gy/25 fractions/5 weeks in phase I followed by randomization (1:1) to further treatment with IMRT (20 Gy/10 fractions/2 weeks) or BT (192Ir high dose rate, 21 Gy/7 fractions/2 fractions per day). The primary endpoint of the trial was the reduction in xerostomia at 6 months evaluated using 99mTc salivary scintigraphy. Severe salivary toxicity (xerostomia) was defined as posttreatment salivary excretion fraction ratio <45%. Secondary endpoints were local control, disease-free survival, and overall survival. RESULTS: Between November 2010 and February 2020, 90 patients were randomized to IMRT (n = 46) alone or IMRT + BT (n = 44). Eleven patients (8 residual/recurrent disease, 2 lost to follow-up, 1 second primary) in the IMRT arm and 9 patients (8 residual/recurrence, 1 lost to follow-up) in the BT arm were not evaluable at 6 months for the primary endpoint. At 6 months, xerostomia rates using salivary scintigraphy were 14% (5/35: 95% CI, 5%-30%) in the BT arm while it was seen in 44% (14/32: 95% CI, 26%-62%) in the IMRT arm (P = .008). Physician-rated Radiation Therapy Oncology Group grade ≥2 xerostomia at any time point was observed in 30% of patients (9/30) in the IMRT arm and 6.7% (2/30) in the BT arm (P = .02). At a median follow-up of 42.5 months, the 3-year local control in the IMRT arm was 56.4% (95% CI, 43%-73%) while it was 66.2% (95% CI, 53%-82%) in the BT arm (P = .24). CONCLUSIONS: The addition of BT to IMRT for T1-T2N0M0 OPSCC results in a significant reduction in xerostomia. This strongly supports the addition of BT to IMRT in suitable cases.

RESUMO

Importance: Patients with early breast cancer must choose between undergoing breast conservation surgery or mastectomy. This decision is often difficult as there are trade-offs between breast conservation and adverse effects, and women with higher decisional conflict have a harder time choosing the therapy that suits their preferences. Objective: To study the impact of a decision aid with a patient preference assessment tool for surgical decision-making on patients' decisional conflict scale (DCS) score. Design, Setting, and Participants: This 3-group randomized clinical trial was conducted between June 2017 and December 2019 at a single high-volume tertiary care cancer center in Mumbai, India. A research questionnaire comprising 16 questions answered on a Likert scale (from 1, strongly agree, to 5, strongly disagree) was used to measure DCS scores and other secondary psychological variables, with higher scores indicating more decisional conflict. The Navya Patient Preference Tool (Navya-PPT) was developed as a survey-based presentation of evidence in an adaptive, conjoint analysis-based module for and trade-offs between cosmesis, adverse effects of radiotherapy, and cost of mandatory radiation following breast-conserving surgery. Adult patients with histologically proven early breast cancer (cT1-2, N0-1) who were eligible for breast-conserving surgery as per clinicoradiological assessment were included. Those who were pregnant or unable to read the research questionnaire or who had bilateral breast cancer were excluded. Data were analyzed from January to June 2020. Interventions: Patients were randomized 1:1:1 to study groups: standard care including clinical explanation about surgery (control), standard care plus the Navya-PPT provided to the patient alone (solo group), and standard care plus the Navya-PPT provided to the patient and a caregiver (joint group). Main Outcomes and Measures: The primary end point of the study was DCS score. The study was 80% powered with 2-sided α = .01 to detect an effect size of 0.25 measured by Cohen d, F test analysis of variance, and fixed effects. Results: A total of 245 female patients (median [range] age, 48 [23-76] years) were randomized (82 to control, 83 to the solo group, and 80 to the joint group). The median (range) pathological tumor size was 2.5 (0-6) cm. A total of 153 participants (62.4%) had pN0 disease, 185 (75.5%) were hormone receptor positive, 197 (80.4%) were human epidermal growth factor receptor 2 negative, 144 (58.6%) were of middle or lower socioeconomic status, and 114 (46.5%) had an education level lower than a college degree. DCS score was significantly reduced in the solo group compared with control (1.34 vs 1.66, respectively; Cohen d, 0.50; SD, 0.31; P < .001) and the joint group compared with control (1.31 vs 1.66, respectively; Cohen d, 0.54; SD, 0.31; P < .001). Conclusions and Relevance: The results of this study demonstrated lower decisional conflict as measured by DCS score following use of the online, self-administered Navya-PPT among patients with early breast cancer choosing between breast-conserving surgery vs mastectomy.

RESUMO

OBJECTIVE: To synthesize the role of secondary cytoreduction in recurrent ovarian cancer from the results of randomized studies. METHODS: We conducted a meta-analysis of randomized controlled trials which compared secondary cytoreductive surgery versus no surgery in patients with platinum sensitive relapsed ovarian cancer. Individual patient data for overall survival and progression free survival were manually extracted from published survival curves, for whole study populations and subgroups based on completeness of surgical resection and bevacizumab use, using WebPlotDigitizer software. Overall survival and progression free survival curves for each study and the combined population were reconstructed from extracted data. RESULTS: Three studies with 1249 patients were included, of whom complete resection was achieved in 427 (34.2%) patients. In individual patient data analysis of the whole study population with 562 deaths, there was no significant difference in overall survival between the surgery and no surgery groups (median 52.8 vs 52.1 months, respectively, hazard ratio (HR) 0.94, 95% confidence interval (CI) 0.80 to 1.11; p=0.5) but the surgery group had significantly longer progression free survival compared with the no surgery group (median 18.3 vs 14.4 months, respectively, HR 0.70, 95% CI 0.62 to 0.80; p<0.001). In subgroup analyses, overall survival was significantly longer in the complete cytoreduction subgroup compared with the no surgery group (median 62.0 vs 52.1 months, respectively, HR 0.70, 95% CI 0.57 to 0.92; p<0.001) while overall survival was significantly worse in the incomplete cytoreduction subgroup compared with the no surgery group (median 34.2 vs 52.1 months, respectively, HR 1.72, 95% CI 1.38 to 2.14; p<0.001). In the no bevacizumab subgroup, there was no significant overall survival difference between the surgery and no surgery groups (median 49.3 vs 47.0 months, HR 0.86, 95% CI 0.67 to 1.10; p=0.25). CONCLUSIONS: Secondary cytoreductive surgery among women with platinum-sensitive relapsed ovarian cancer did not lead to significant benefit in overall survival although it increased progression free survival. However, overall survival was significantly longer among patients in whom complete cytoreduction was possible compared with no surgery.

RESUMO

BACKGROUND: Translationally controlled tumour protein (TCTP) is a multifunctional protein elevated in multiple cancers. However, studies on its role in oral carcinogenesis and prognosis are rare. We recently reported the role of its interacting partner, MCL1, in oral cancer progression and outcome. Hence, the present study aimed to assess TCTP expression in oral tumorigenesis and its association with patient outcomes alone and in combination with MCL1. METHODS: TCTP expression was assessed by immunohistochemistry and immunoblotting in oral tissues and cells, respectively. Cell viability post siRNA/dihydroartemisinin treatment was analysed by tetrazolium salt assay. Cell survival, invasion and tumorigenic potential post TCTP knockdown were assessed by clonogenic, Matrigel and soft-agar assays, respectively. The association of TCTP with patient outcome was analysed by Kaplan-Meier and Cox regression. RESULTS: TCTP was significantly overexpressed in oral premalignant lesions (p < 0.0001), oral tumours (p < 0.0001) and oral dysplastic and cancer cells versus normal oral mucosa and also in recurrent (p < 0.05) versus non-recurrent oral tumours. Further, elevated TCTP was significantly (p < 0.05) associated with poor recurrence free survival (RFS) and poor overall survival (OS; hazard ratio = 2.29; p < 0.05). Intriguingly, the high co-expression of TCTP and MCL1 further reduced the RFS (p < 0.05) and OS (p < 0.05; hazard-ratio = 3.49; p < 0.05). Additionally, TCTP knockdown decreased survival (p < 0.05), invasion (p < 0.01) and in vitro tumorigenic potential (p < 0.0001). Dihydroartemisinin treatment reduced TCTP levels and viability of oral cancer cells. CONCLUSION: Our studies demonstrate an oncogenic role of TCTP in oral cancer progression and poor outcome. Thus, TCTP may be a potential prognostic marker and therapeutic target in oral cancers.

RESUMO

Background: Contemporary standard-of-care for newly diagnosed glioblastoma (GBM) is maximal safe resection followed by postoperative focal conformal radiotherapy (RT) plus concurrent temozolomide (TMZ) and 6-cycles of adjuvant TMZ (Stupp regimen). However, many patients continue to receive extended adjuvant TMZ (beyond 6-cycles) without solid scientific evidence. This review pools data from nonrandomized studies and randomized controlled trials (RCTs) comparing extended adjuvant TMZ (>6-cycles) to standard adjuvant TMZ (6-cycles) in patients with newly diagnosed GBM for updated evidence-synthesis. Methods: This systematic review and meta-analysis was carried out in accordance with the Cochrane methodology including quality assessment of primary studies. Primary outcome of interest was comparative efficacy defined as progression-free survival (PFS) and overall survival (OS). Hazard ratios (HRs) for PFS and OS with corresponding 95% confidence interval (CIs) were extracted/computed from individual primary studies and pooled using random-effects model. Any p-value <0.05 was considered statistically significant. Results: Evidence-synthesis was based on pooling of data from 2578 patients enrolled in 16 nonrandomized comparative studies and 5 RCTs. Overall, extended adjuvant TMZ was associated with statistically significant reduction in the risk of progression (HR = 0.72, 95%CI: 0.60-0.87; p = 0.007) and death (HR = 0.71, 95%CI: 0.57-0.90; p = 0.004) compared to standard adjuvant TMZ. However, on subgroup analysis, survival benefit of extended adjuvant TMZ was limited to data synthesized from retrospective nonrandomized comparative studies with no statistically significant difference in outcomes seen after pooling of data from RCTs only. Conclusion: Apparent survival benefit of extended adjuvant TMZ in newly diagnosed GBM is largely driven by nonrandomized comparative studies with high inherent potential for multiple biases.

RESUMO

BACKGROUND: In hematopoietic stem cell transplant (HSCT), vitamin D deficiency has been variably associated with increased complications, primarily graft versus host disease (GvHD), with a potential impact on survival. Results from various studies however, have not been consistent. This analysis was conducted to study the impact of peri-transplant vitamin D levels on transplant outcomes in patients with acute leukemia (AL) who underwent HLA matched (related/unrelated) HSCT. METHODS: This was a single center retrospective study. Patients of AL including Acute Lymphoblastic Leukemia (ALL), Acute Myeloid Leukemia (AML) or Mixed Phenotypic Acute Leukemia (MPAL) who underwent fully matched or 9/10 transplants (related/unrelated) between 2008 and 2019 were included. Vitamin D deficiency was defined as serum 25-hydroxy vitamin D3 levels ≤20 ng/ml. Those with deficiency received replacement with oral vitamin D at a dose of 60,000 IU weekly for 8 weeks followed by maintenance with daily vitamin D (800 IU/day). Vitamin D levels were repeated at 4 months from start of replacement. For patients who received correction, repeat levels >20 ng/ml were considered replete. Based on vitamin D levels in the peri-transplant period (within 120 days of transplant), patients were categorised as either vitamin D replete (> 20 ng/ml) or deplete (≤ 20 ng/ml). Peri-transplant vitamin D status was correlated with transplant outcomes. RESULTS: Of the 133 patients included, 31 were deplete (median vitamin D 15.0 ng/ml) and 102 were replete (median vitamin D 34 ng/ml) at time of transplant. Both groups were matched for age, diagnosis, EBMT score and disease risk index (DRI). There were no differences in time to neutrophil or platelet engraftment, CMV reactivation, acute GvHD (aGvHD) or chronic GvHD (cGvHD) between the two groups. Relapse rate, Progression Free Survival (PFS) and Overall Survival (OS) were also comparable between the 2 groups. CONCLUSION: The incidence of vitamin D deficiency was high in our patient cohort. Patients who were vitamin D deficient at the time of transplant did not have inferior outcomes, suggesting a limited role of vitamin D in influencing transplant outcomes.

RESUMO

Purpose: Antifungal prophylaxis with posaconazole has demonstrated a reduction in the risk of death due to Invasive fungal infections (IFI)in patients with acute myeloid leukemia (AML) during induction therapy. However, various factors affect the plasma levels of posaconazole and can potentially limit its efficacy. Therapeutic drug monitoring (TDM) can help optimize the dose, but literature is scant from centers with a high IFI burden. This study aimed to evaluate the proportion of de-novo AML patients on induction who could achieve the target level of 700ng/mL with posaconazole prophylaxis,factors that can influence the plasma levels, and the impact of plasma posaconazole levels on incidence of IFI. Methods: Patients with AML on induction therapy with no baseline IFI were enrolled at our tertiary cancer center which has high prevalence of IFI. These patients received posaconazole suspension as prophylaxis. Daily plasma levels were measured from Day 4 till Day 12 of posaconazole prophylaxis. All patients were monitored for the development of IFI. The data on adverse events, concomitant drugs, mucositis, vomiting, and diarrhea were recorded. Results: A total of 411 samples from fifty patients were collected. Only 177 out of 411 samples had levels > 700 ng/mL. The median trough level was 610 ng/mL (range30-3000 ng/mL). The median time to achieve target trough concentration was four days (range 4-12 days) from the start of induction.Thirty-eight (76%) patients achieved target plasma levels by day 12 of induction.The median plasma level on day 12 was 690 ng/mL (range,30-1270) in patients who achieved target levels as compared to 340 (50-560) ng/mL in those who did not. Twenty-six (52%) patients had IFI in our study, and the median time to develop breakthrough IFI was 14 days (range 4-24 days). Median and range of plasma levels were 690 ng/ml (30-2410; n = 22) in those who developed IFI, while 590 ng/mL (50-2300 n = 24) in those who did not. The odds of developing IFI in patients who did not achieve the threshold trough concentration of 700 ng/mL was 7.14 (95% CI; 1.35-37.75, p = 0.0206). Occurrence of vomiting (p = 0.02), diarrhea (p = 0.0008), mucositis (p = 0.003) had adverse impact on achievement of target plasma posaconazole levels. Conclusion: A significant proportion of patients receiving posaconazole prophylaxis fail to achieve target plasma levels which can result in high risk of development of IFI.

RESUMO

Background and Aims: The analgesic role of gabapentinoids following thoracic surgeries is not clear. In this study, we evaluated the benefits of gabapentinoids for pain management in patients undergoing thoracic onco-surgery in terms of opioids and non-steroidal anti-inflammatory drugs (NSAIDs) sparing effect. We also compared pain scores (PSs), number of days of active surveillance by the acute pain service team, and side effects associated with gabapentinoids. Methods: After ethics-committee approval, data were retrieved retrospectively from clinical sheets, an electronic database, and nurses' charts from a tertiary cancer care hospital. Propensity score matching was performed for six covariates, that is, age, gender, American Society of Anesthesiologists grading, surgical approach, analgesia modality, and worst PS in the first 24 hours performed. A total of 272 patients were grouped into group N (not given gabapentinoids, n = 174) and group Y (given, n = 98). Results: The median opioid consumption in terms of fentanyl equivalent by group N was 800 µg [inter-quartile range (IQR): 280-900], and the median opioid consumption by group Y was 400 µg (IQR: 100-690) (p = 0.001). The median number of rescue doses of NSAIDs administered to group N was 8 (IQR = 4-10), and the median number of rescue doses to group Y was 3 (IQR = 2-5) (p = 0.001). No difference was found in subsequent PS and for the number of days under acute pain service surveillance for either group. Group Y had an increased incidence of giddiness compared to group N (p = 0.006), with a relative reduction in post-operative nausea and vomiting scores (p = 0.32). Conclusion: Gabapentinoids used following thoracic onco-surgeries result in a significant reduction in concomitant use of NSAIDs and opioids. There is an increased incidence of dizziness with the use of these drugs.

RESUMO

BACKGROUND: Cervical cancer is one of the most common cancers in women with an incidence of around 6.5 % of all the cancer in women worldwide. Early detection and adequate treatment according to staging improve the patient's life expectancy. Outcome prediction models might aid treatment decisions, but a systematic review on prediction models for cervical cancer patients is not available. DESIGN: We performed a systematic review for prediction models in cervical cancer following PRISMA guidelines. Key features that were used for model training and validation, the endpoints were extracted from the article and data were analyzed. Selected articles were grouped based on prediction endpoints i.e. Group1: Overall survival, Group2: progression-free survival; Group3: recurrence or distant metastasis; Group4: treatment response; Group5: toxicity or quality of life. We developed a scoring system to evaluate the manuscript. As per our criteria, studies were divided into four groups based on scores obtained in our scoring system, the Most significant study (Score > 60 %); Significant study (60 % > Score > 50 %); Moderately Significant study (50 % > Score > 40 %); least significant study (score < 40 %). A meta-analysis was performed for all the groups separately. RESULTS: The first line of search selected 1358 articles and finally 39 articles were selected as eligible for inclusion in the review. As per our assessment criteria, 16, 13 and 10 studies were found to be the most significant, significant and moderately significant respectively. The intra-group pooled correlation coefficient for Group1, Group2, Group3, Group4, and Group5 were 0.76 [0.72, 0.79], 0.80 [0.73, 0.86], 0.87 [0.83, 0.90], 0.85 [0.77, 0.90], 0.88 [0.85, 0.90] respectively. All the models were found to be good (prediction accuracy [c-index/AUC/R2] >0.7) in endpoint prediction. CONCLUSIONS: Prediction models of cervical cancer toxicity, local or distant recurrence and survival prediction show promising results with reasonable prediction accuracy [c-index/AUC/R2 > 0.7]. These models should also be validated on external data and evaluated in prospective clinical studies.

RESUMO

Background & objectives: FOLFIRINOX and gemcitabine plus nab-paclitaxel (GN) are the most commonly used regimens in advanced pancreatic ductal adenocarcinomas (PDACs). As there is limited data on comparison of these two regimens, the present study was aimed to compare survivals and tolerance for both regimens through a match-pair analysis. Methods: The data of 350 patients with metastatic and locally advanced PDAC, treated between January 2013 and December 2019, were retrieved. A 1:1 matching, using age and performance status, without replacement was performed by using nearest neighbour matching method. Results: A total of 260 patients (130 modified FOLFIRINOX and 130 GN) were matched. The median overall survival (OS) was 12.98 months [95% confidence interval (CI) 7.257-8.776 months] in modifications of FOLFIRINOX (mFOLFIRINOX) cohort and 12.06 months (95% CI 6.690-8.88 months) in GN group (P=0.080). The incidence of grade 3 and 4 infections, diarrhoea, oral mucositis, and fatigue was higher with mFOLFIRINOX. Patients who received second line therapy had improved OS as compared to those who did not (14.06 vs. 9.07 months, P<0.001). Interpretation & conclusions: GN and mFOLFIRINOX appear to have similar survival outcomes in an unselected match paired patient population with advanced PDAC. A markedly increased incidence of non-myelosuppressive grade 3 and grade 4 side-effects and lack of survival improvements suggest a need for nuanced use of the mFOLFIRINOX regimen. Administration of second-line chemotherapy improves OS in patients with advanced PDAC.

RESUMO

BACKGROUND: To assess the efficacy of prophylactic versus reactive feeding strategy in oral cavity squamous cell carcinoma (OCSCC) patients receiving adjuvant radiation therapy (RT). METHODS: This was a post hoc analysis of patients of OCSCC enrolled in a randomized trial comparing three adjuvant strategies. In this trial, till 2010, a prophylactic feeding approach was followed for all patients. Since January 2011, a reactive feeding approach was followed. RESULTS: Two hundred and sixty-eight in each cohort (total n = 526) were eligible for analysis after propensity score matching. At 6 weeks post-RT completion, the median weight loss in the prophylactic versus reactive cohort was 5 versus 3 kg, p = 0.002. At all other time points until 1 year, the median weight loss was lesser in reactive than in the prophylactic cohort. CONCLUSIONS: A reactive feeding tube approach should be preferred for OCSCC receiving adjuvant RT.

RESUMO

PURPOSE: To report clinical and treatment characteristics, remission and failure patterns, and risk factors for local failure (LF) from the EMBRACE-I study. MATERIALS AND METHODS: EMBRACE-I was a prospective, observational, multicenter cohort study on magnetic resonance imaging-based image-guided adaptive brachytherapy (MR-IGABT) in locally advanced cervical cancer. Treatment consisted of external beam radiotherapy, concurrent chemotherapy, and MR-IGABT. LF was defined as progressive or recurrent disease in the cervix, uterus, parametria, pelvic wall, or vagina. Competing risk analysis was used to estimate local tumor control (LC) and Cox proportional regression models for multivariable analysis and dose-response analysis. RESULTS: One thousand three hundred eighteen patients with a median follow-up of 52 months were available for this analysis. Eighty-one patients had persistent disease 3 months after end of treatment. Of those, 60 patients achieved LC at 6-9 months without further treatment, whereas 21 patients had progressive disease. In addition, 77 patients developed a local recurrence after complete remission comprising a total number of 98 LFs. LFs were located inside the MR-IGABT target volumes in 90% of patients with LF. In multivariable analysis, histology, minimal dose to 90% of high-risk clinical target volume (CTVHR), maximum tumor dimension, CTVHR > 45 cm3, overall treatment time, tumor necrosis on magnetic resonance imaging at diagnosis, uterine corpus infiltration at diagnosis and at MR-IGABT, and mesorectal infiltration at MR-IGABT had significant impact on LF. Dose-response analysis showed that a minimal dose to 90% of 85 Gy to the CTVHR led to 95% (95% CI, 94 to 97) LC 3 years postintervention for squamous cell in comparison to 86% (95% CI, 81 to 90) for adeno/adenosquamous carcinoma histology. CONCLUSION: The present study demonstrates the safety and validity of the GYN GEC-ESTRO/ICRU-89 target concept and provides large-scale evidence for dose prescription and new risk factors for LF in MR-IGABT in locally advanced cervical cancer.

RESUMO

Outcomes with DLI alone for post-transplant relapsed hematological malignancies are poor especially in acute leukemias. Addition of immunomodulatory drugs to DLI may augment GVL effect. Use of lenalidomide with DLI to augment GVL has not been previously reported. This retrospective analysis was to compare the outcomes of DLI with or without lenalidomide. All consecutive patients who received DLI from 01/2010 through 01/2020 were included. DLIs were given without any immunosuppression. Lenalidomide, when used, was given continuously, starting with 1st or subsequent DLI. Patients who received lenalidomide were compared with those who did not. Event (hematological relapse or death) free survival (EFS) and overall survival (OS) were calculated from 1st DLI. Primary objective was to compare OS. Secondary objectives were EFS, CR rates, acute GVHD, lenalidomide toxicities and DLI related mortality (TRM). Total 61 patients received DLI-43 without and 18 with lenalidomide; all outcomes in the 2 groups were similar. There were 26 patients with HLA-A*24 and/or HLA-B*40. Among these, trend towards improvement in OS (median OS not reached vs. 8 months, 4 year OS was 62% vs. 32%, p = 0.1) and EFS (median 9 vs. 1 month, 4 year EFS 50% vs. 22%, p = 0.1) was seen with lenalidomide. Overall, there was no improvement in outcomes by adding lenalidomide to DLI. However, among patients with HLA*24 or B*40, there was a trend to improved survival with lenalidomide. Use of lenalidomide to augment the GVL effect of DLI warrants further exploration.

RESUMO

BACKGROUND AND OBJECTIVES: There is limited real-world data on the efficacy of 2-weekly cycles of docetaxel, oxaliplatin, leucovorin, and fluorouracil (FLOT) compared to epirubicin, oxaliplatin, and capecitabine (EOX) as perioperative therapy in esophagogastric adenocarcinomas (EGAC). METHODS: The data of 611 patients with EGAC treated with perioperative chemotherapy and planned for curative resection between January 2013 and December 2019 were retrieved. Patients receiving EOX and a dose-modified version of FLOT (mFLOT) were evaluated. A 1:1 matching, using age, tumour location, signet ring histology, and Eastern Cooperative Oncology Group performance status, without replacement was performed by using nearest neighbour matching method. The primary endpoint of the study was 3-year event-free survival (EFS). RESULTS: A total of 593 patients (261 with EOX and 332 with mFLOT) were matched. One hundred and nighty-eight patients (76%) and 285 patients (86%) in the EOX and mFLOT cohorts underwent curative resection, respectively (p = 0.002). With a median follow-up of 35 and 53 months, respectively, the primary outcome of 3-year EFS was statistically superior in patients receiving mFLOT as compared to the EOX regimen (60% vs. 39%; p < 0.001). There was a greater incidence of grade 3 and grade 4 neutropenia (neoadjuvant: 18% vs. 2%; p < 0.001, adjuvant: 18% vs. 1%; p = 0.001) and febrile neutropenia (neoadjuvant: 8% vs. 1.1%; p < 0.001, adjuvant: 6% vs. 0; p = 0.001) with mFLOT. INTERPRETATION AND CONCLUSION: mFLOT is associated with improved resection rates and survival in comparison to EOX as perioperative therapy in gastric adenocarcinomas in this large real-world cohort, with manageable increase in clinically relevant toxicities such as grade 3 and grade 4 febrile neutropenia and neutropenia.
