Primary plasma cell leukemia (pPCL) is an uncommon disease. IgM multiple myeloma (MM) is an infrequent subtype that accounts for less than 1 percent of MM cases. IgM pPCL is quite rare with only a few cases published to date. We describe a case of a patient with IgM pPCL who initially presented with hyperviscosity syndrome requiring urgent plasma exchange. His bone marrow biopsy demonstrated t(11;14). He progressed on proteasome inhibitors, immunomodulating agents, and other chemotherapy medications but later achieved very good partial response (VGPR) to venetoclax and dexamethasone. Given the poor prognosis of pPCL, further studies using venetoclax alone or in combination with other novel agents as first-line treatment options are warranted particularly in patients with t(11;14).
e16067 Background: The clinical and mutational profile of Hispanic patients with metastatic colon cancer is not well documented. In this retrospective study, we aim to describe the clinical and mutational profile of Hispanic patients with metastatic colon cancer in central California. Methods: We retrospectively evaluated the clinical and mutational profile of colon cancer at a single institution in Fresno, California from 2010-2019. We selected 136 patients out of which 70 patients self-identified as Hispanic and 66 self-identified as non-Hispanic. We studied clinical parameters and next-generation sequencing via Foundation one testing for these patients. Results: Among Hispanics, there were 43(61%) males and 27(38%) females. The median age at diagnosis was similar in both groups at 57. Right sided colon cancer accounted for 52% of Hispanic patients versus 40% in non-Hispanics. Fifty two percent of Hispanic patients presented with metastatic disease versus 45% in non-Hispanics. The frequency of commonly mutated genes in colon cancer in Hispanics versus non-Hispanics are as follows. KRAS (35.7% vs 37%), NRAS (11% vs 4%) BRAF (8% vs 7%), Her2/neu 0% in both groups. The frequency of other mutations such as TP53, APC, ATM, PTEN, CDKN2A, Myc amplification were also noted to be similar in both groups. PIK3CA mutation was seen in 18.6% of Hispanic patients versus 34% in non-Hispanic population which was statistically significant with a p value = 0.032. Microsatellite instability (MSI) was seen at 3.3% in Hispanics versus 10.6% in non-Hispanics. Tumor mutational burden was similar in both groups. Conclusions: The frequency of actionable mutations was similar in both Hispanic and non-Hispanic patients. Hispanics were noted to have lower PIK3CA and microsatellite instability. Metastatic disease and right sided colon cancer were seen at higher frequency in Hispanic population. Our results were similar to another population-based study which analyzed KRAS mutation with colon cancer patients in Puerto Rico[1]. Larger population based studies would be needed to further assess the differences in this patient population. Ruiz-Candelaria, Y., C. Miranda-Diaz, and R.F.

Bladder adenocarcinoma is an uncommon type of bladder cancer. Signet ring cell pathology is a rare subtype of bladder adenocarcinoma. Global incidence rates of signet ring cell adenocarcinoma of the bladder have not been established. Management of signet cell bladder cancer is challenging as it is aggressive in behavior with frequent relapse despite chemotherapy. Here we present a case of stage IV signet cell bladder cancer with retroperitoneal fibrosis treated with FOLFOX (folinic acid, 5-fluorouracil, oxaliplatin) regimen with a complete durable response.
Ordering chemotherapy within an Electronic medical record (EMR) can be a seamless process while working in a resource-rich setting. Implementing it in a under resourced setting can be challenging. Binaytara Foundation Cancer Center recently started using Karexpert EMR for inpatient and outpatient use. This was a major step in creating a paper-free experience at the hospital. However, Karexpert lacked the functionality to order chemotherapy within the EMR. The administration of chemotherapy is a complex process involving various stages, including drug protocol selection, dosage calculation, and schedule planning. The use of an electronic medical record (EMR) system facilitates the implementation of a chemotherapy order set and improve the safety and efficiency of the treatment process. We are documenting our experience of implementing chemotherapy order sets in Karexpert at Binaytara Foundation Cancer Center.Hinduja S, Mallik S, Games D, Shah B.

Androgen deprivation therapy has been the mainstay of treatment for management of metastatic hormone sensitive prostate cancer. Recently conducted randomized controlled trials with docetaxel based chemotherapy have shed light on benefit of early use chemotherapy for hormone sensitive prostate cancer. In this review, we aim to comprehensively describe recent trials which are changing the paradigm in support of up front use of docetaxel based chemotherapy for metastatic hormone sensitive prostate cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
