Sarcopenia is an independent predictor of complications following pancreatectomy for adenocarcinoma

Sarcopenia, which is subclinical loss of skeletal muscle mass, is commonly observed in patients with malignancy. The objective of this study is to determine the correlation between sarcopenia and operative complications following pancreatectomy for cancer.

Bone marrow sparing in intensity modulated proton therapy for cervical cancer: Efficacy and robustness under range and setup uncertainties

BACKGROUND AND PURPOSEnThis study evaluates the potential efficacy and robustness of functional bone marrow sparing (BMS) using intensity-modulated proton therapy (IMPT) for cervical cancer, with the goal of reducing hematologic toxicity.nnnMATERIAL AND METHODSnIMPT plans with prescription dose of 45 Gy were generated for ten patients who have received BMS intensity-modulated X-ray therapy (IMRT). Functional bone marrow was identified by (18)F-flourothymidine positron emission tomography. IMPT plans were designed to minimize the volume of functional bone marrow receiving 5-40 Gy while maintaining similar target coverage and healthy organ sparing as IMRT. IMPT robustness was analyzed with ±3% range uncertainty errors and/or ±3 mm translational setup errors in all three principal dimensions.nnnRESULTSnIn the static scenario, the median dose volume reductions for functional bone marrow by IMPT were: 32% for V(5Gy), 47% for V(10Gy), 54% for V(20Gy), and 57% for V(40Gy), all with p<0.01 compared to IMRT. With assumed errors, even the worst-case reductions by IMPT were: 23% for V(5Gy), 37% for V(10Gy), 41% for V(20Gy), and 39% for V(40Gy), all with p<0.01.nnnCONCLUSIONSnThe potential sparing of functional bone marrow by IMPT for cervical cancer is significant and robust under realistic systematic range uncertainties and clinically relevant setup errors.

Immunoglobulin replacement therapy reduces chronic rhinosinusitis in patients with antibody deficiency.

Patients with primary antibody deficiencies have an increased frequency of sinonasal and pulmonary infections. Immunoglobulin (Ig) replacement is a standard therapy for common variable immunodeficiency (CVID) and other antibody deficiency diseases. Although there is convincing evidence that Ig replacement reduces pulmonary infections, there is little evidence that it reduces sinus infections or abates chronic rhinosinusitis (CRS). This study aims to identify the impact of Ig replacement on CRS in antibody deficiencies.

VTD-melphalan is well tolerated and results in very high rates of stringent CR and MRD-negative status in multiple myeloma

The addition of cytotoxic drugs to high-dose melphalan as a preparative regimen for autologous stem cell transplantation in multiple myeloma has not resulted in superior activity. Although novel agents have significantly improved outcome in multiple myeloma, their role in preparative regimens remains largely unknown. We have evaluated the toxicity and efficacy of combining bortezomib, thalidomide, and dexamethasone with high-dose melphalan. An institutional review board-approved retrospective analysis was performed on 100 consecutive patients receiving 153 transplants; 53 had tandem transplants; 64 patients received early transplants; and 36 had salvage transplantation. Endpoints were treatment-related toxicity and mortality, and quality of response post-transplantation with assessment of stringent complete remission (sCR) and minimal residual disease (MRD) status. Median age was 61 years, and median follow-up was 16.2 months. At 6 months, sCR was attained in 56% of patients and CR in 20%. An MRD status, assessed by sensitive (10−4) multiparameter flow cytometry, was achieved in 85%. The 100-day mortality rate was 2.6% (4/153); 1.8% for early transplants and 4.5% for salvage transplants. Grade 3–5 non-hematologic toxicities were mainly related to metabolism/nutrition; gastrointestinal and infectious problems. Median time to absolute neutrophil count of >500/µL was 12 days for both early and salvage transplantations. No significant differences in quality of response were observed between early and salvage transplantation or between single and tandem autologous stem cell transplantation. Since both sCR and MRD are excellent early surrogate markers for progression-free and overall survival, this regimen will likely be superior to melphalan alone, but it needs to be formally assessed in a randomized study.

Health-related quality of life in patients with cutaneous T-cell lymphoma?

Little is currently known about health‐related quality of life (HRQoL) of patients with cutaneous T‐cell lymphoma (CTCL), a condition characterized by chronic, pruritic, visible lesions, features which may be uniquely influential.

C-Reactive Protein Monitoring Predicts Neutropenic Fever Following Autologous Hematopoietic Stem Cell Transplantation for Multiple Myeloma

Background Neutropenic fever (NF) is a known and common complication of autologous hematopoietic stem cell transplantation (ASCT). Early risk assessment may help direct treatment. We retrospectively analyzed the role of serial serum C-reactive protein (CRP) levels in predicting NF and assessed the clinical value of CRP within 14 days after transplantation. Methods One hundred twenty-one multiple myeloma (MM) patients received 170 first and/or second ASCT between January 2014 and March 2017. A Cox regression model was applied to assess the prognostic value of CRP as a time-dependent covariate at the onset of NF within 14 days post-transplant. Results Forty-seven of 170 patients developed NF. High CRP levels (4.0–43.2 mg/dL) were associated with a 5.45-fold increased risk of NF (P = 0.02). Patients had a nearly three-fold increased risk of NF after the second transplant (P < 0.01), but this was not associated with increased mortality. Those with NF had higher maximum values of CRP (P < 0.01) which tended to occur at or after the onset of NF. Conclusion CRP monitoring provides important information about the risk for NF immediately after first MM ASCT, and even more so after the second.

Bloodless tandem autologous transplant in Jehovah’s Witness patients

Tandem autologous transplants are generally the preferred therapy for newly diagnosed intermediate- and high-risk myeloma patients. More Jehovah’s Witnesses (JW) are receiving single autologous peripheral blood stem cell transplants (PBSCTs). However, tandem autologous transplants have not been reported in JW patients. We performed a retrospective study of 54 patients, including four JW patients who received tandem autologous transplants between August 2000 and January 2017 and the last 50 consecutive tandem autologous transplants performed between August 2014 and August 2016. The bleeding complications, number, and cost of transfusions of blood products were compared. The median number of CD34 cells infused in non-JW patients was 8.16 million cells/kg versus 9.44 million cells/kg in JW patients. During the first 30 days, one JW experienced Grade III pulmonary hemorrhage, while none of the non-JW patients had a Grade III or higher bleeding problem. After tandem autologous transplants, complete remission was achieved in 88% of non-JW, compared with 75% in JW patients. In the first 30 days post-transplant, median platelet and packed red blood cell (PRBC) transfusions in non-JW patients was 2 (range: 0–40) and 1 (range: 0–11), respectively. Total cost of PRBC and platelet transfusions for the 50 non-JW was

The impact of prostate cancer (PC) margin extent (ME) at radical prostatectomy (RP) on biochemical relapse-free survival (bRFS).

To quantify variations in the reporting of ultrasound characteristics of adnexal masses between local ultrasound centers and a tertiary care center for women referred to gynecologic oncology for evaluation of a pelvic mass. This study also sought to evaluate whether a gynecologic oncologist’s impression regarding the suspicion for malignancy differed based upon the information provided in the local ultrasound report as compared to the tertiary care center ultrasound report.
