Psycho-oncology Jan 2014Procarbazine is an anticancer agent that also inhibits monoamine oxidase, an enzyme responsible for the metabolism of various catecholamines, including serotonin.
BACKGROUND
Procarbazine is an anticancer agent that also inhibits monoamine oxidase, an enzyme responsible for the metabolism of various catecholamines, including serotonin.
METHODS
A retrospective chart review of lymphoma patients who were treated with both procarbazine and an antidepressant, as well as procarbazine alone, was performed to determine if signs and symptoms of serotonin toxicity were present.
RESULTS
A total of 65 patients received procarbazine between 2004 and 2010 and were eligible to be included in the study. Twenty-six of these patients received an antidepressant in combination with procarbazine, with selective serotonin reuptake inhibitors being the most common type of antidepressant. No patients in the study were diagnosed with serotonin toxicity, nor did any meet Hunter's diagnostic criteria for serotonin toxicity. Diarrhea, tremor, and shivering were the symptoms from Sternbach's criteria that were further analyzed, with diarrhea occurring 8.54% of the time, tremor occurring 5.53% of the time, and shivering occurring 2.51% of the time in patients who received an antidepressant with their procarbazine. Despite these symptoms, the diagnosis of serotonin toxicity according to Sternbach's criteria was determined to be unlikely.
CONCLUSIONS
In this small sample of patients treated with procarbazine plus an antidepressant (most typically SSRIs), there were no reports of serotonin toxicity, nor did any patients demonstrate symptoms consistent with serotonin toxicity. The authors urge clinicians to ensure depression is adequately managed in cancer patients who are undergoing procarbazine therapy, starting with typical first-line antidepressant agents.

Review
The risk of developing premature ovarian failure and azoospermia is a major concern in long-term survivors treated for Hodgkin's lymphoma. Alkylating chemotherapy containing procarbazine and/or cyclophosphamide causes prolonged azoospermia in 90-100% of men and premature ovarian failure in 5-25% of women under the age of 30. The risk of infertility increases with the cumulative dose of alkylating agents and the risk is high after salvage therapy including conditioning and autologous or allogeneic transplantation. The doxorubicin-bleomycin-vinblastine-dacarbazine regimen is associated with a lower risk of gonadal damage; the rate of infertility is less than 10%. The risk of premature ovarian failure is limited after the doxorubicin-bleomycin-vinblastine-dacarbazine regimen. However, age is an important factor; women over 30 years of age are at a much higher risk of ovarian failure. Semen cryopreservation should be routinely offered, especially before initial treatment with bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisolone or salvage therapy with high-dose chemotherapy and autologous transplantation. For women with a stable partner, in vitro fertilization for embryo cryopreservation is a routine procedure but can only be offered to a small number of patients and requires a delay in treatment initiation for at least four weeks. Cryopreservation of mature or immature oocytes remains experimental. Ovarian tissue cryopreservation is promising but has so far resulted in only a small number of pregnancies and births. This method, usually involving the removal of an entire ovary, is only proposed before treatment leading to a high risk of infertility. Analogs of LHRH were investigated in order to preserve fertility in women but are not recommended in the absence of studies demonstrating their effectiveness. The risk of secondary infertility should be discussed with patients from the time of the diagnosis and requires multidisciplinary collaboration between hematologists and Assisted Reproductive Techniques (ART) teams.

Medicine Sep 2020Systematic evaluation of the effectiveness and safety of combined procarbazine, lomustine, and vincristine for treating recurrent high-grade glioma.
A comparative study of the effectiveness and safety of combined procarbazine, lomustine, and vincristine as a therapeutic method for recurrent high-grade glioma: A protocol for systematic review and meta-analysis.
BACKGROUND
Systematic evaluation of the effectiveness and safety of combined procarbazine, lomustine, and vincristine for treating recurrent high-grade glioma.
METHODS
Electronic databases including PubMed, MEDLINE, EMBASE, Cochrane Library Central Register of Controlled Trials, WanFang, and China National Knowledge Infrastructure (CNKI) were used to search for studies related to the utilization of combined procarbazine, lomustine, and vincristine as a therapeutic method for recurrent high-grade glioma. Literature screening, extraction of data, and evaluation of high standard studies were conducted by 2 independent researchers. The robustness and strength of the effectiveness and safety of combined procarbazine, lomustine, and vincristine as a therapeutic methodology for recurrent high-grade glioma was assessed based on the odds ratio (OR), mean differences (MDs), and 95% confidence interval (CI). RevMan 5.3 software was used for carrying out the statistical analysis.
RESULTS
These results obtained in this study will be published in a peer-reviewed journal.
CONCLUSION
Evidently, the conclusion of this study will provide an assessment on whether combined procarbazine, lomustine, and vincristine provides an effective and safe form of treatment for recurrent high-grade glioma.

Background The role of Procarbazine Lomustine and Vincristine (PCV) chemotherapy is already established in terms of improving survival in low-grade glioma (LGG). This improved survival has led to the increasing administration of PCV to LGG patients over the past years. However, like other chemotherapies, serious hematological and non-hematological toxicities may occur. The purpose of this study was to evaluate the toxicity profile of PCV and its clinical relevance in our practice. Materials and Methods We reviewed 63 patients of LGG retrospectively who received chemotherapy PCV between January 2015 and January 2018 at Shaukat Khanum Memorial Cancer Hospital & Research Centre, Lahore. Results Significant hematological toxicity as grade 3 anemia, thrombocytopenia, and neutropenia occurred in 19%, 27%, and 46% respectively with PCV. Other toxicities such as neurotoxicity, vomiting and derangement of liver enzymes occurred in 3.2%, 19%, and 19% respectively. Patients who were on concurrent anticonvulsants had no increase in PCV toxicity. Survival was not impacted by hematological toxicities up to grade 3. Conclusion PCV chemotherapy is associated with major hematological, hepatic, and clinical toxicities (vomiting, constipation, and neuropathy). Hematological toxicities influenced the course of treatment in terms of delays and interruptions.

OBJECTIVES
The aims of this study were to evaluate the safety of mustargen, vincristine, procarbazine and prednisone (MOPP) chemotherapy in the treatment of relapsed or refractory feline lymphoma, and to determine the overall response rate and median remission time with this protocol.
METHODS
The medical records of 38 cats with relapsed or refractory lymphoma treated with MOPP chemotherapy at three institutions (University of Pennsylvania, the Animal Medical Center, and VCA Western Veterinary Specialist and Emergency Centre) were examined. Information evaluated included patient signalment, feline immunodeficiency virus/feline leukemia virus status, anatomic location(s) of lymphoma, prior protocols (type and number), MOPP doses, MOPP response, remission duration, hematologic and biochemical parameters, and owner-reported adverse effects.
RESULTS
Overall, 70.3% of cats responded to MOPP chemotherapy. Among the responders, the median remission duration was 166 days. The most common adverse effects were neutropenia and gastrointestinal upset, which were reported in 18.4% of cats. In 55.3% of cats, no adverse effects were reported. In total, 30.8% of responders continued to respond 6 months following the initiation of MOPP, and 15.4% maintained a response 1 year after starting MOPP.
CONCLUSIONS AND RELEVANCE
MOPP is a safe protocol for the treatment of relapsed or refractory feline lymphoma, with a promising overall response rate and median remission time.

Oligodendrogliomas are a subtype of adult diffuse glioma characterized by their better responsiveness to systemic chemotherapy than other high-grade glial tumors. The World Health Organization (WHO) 2021 brain tumor classification highlighted defining molecular markers, including 1p19q codeletion and IDH mutations which have become key in diagnosing and treating oligodendrogliomas. The management for patients with oligodendrogliomas includes observation or surgical resection potentially followed by radiation and chemotherapy with PCV (Procarbazine, Lomustine, and Vincristine) or Temozolomide. However, most of the available research about oligodendrogliomas includes a mix of histologically and molecularly diagnosed tumors. Even data driving our current management guidelines are based on subgroup analyses of the 1p19q codeleted population in landmark prospective trials. Therefore, the optimal treatment paradigm for molecularly defined oligodendrogliomas is incompletely understood. Many questions remain open, such as the optimal timing of radiation and chemotherapy, the response to different chemotherapeutic agents, or what genetic factors influence responsiveness to these agents. Ultimately, oligodendrogliomas are still incurable and new therapies, such as targeting IDH mutations, are necessary. In this opinion piece, we present relevant literature in the field, discuss current challenges, and propose some studies that we think are necessary to answer these critical questions.

BACKGROUND
Hodgkin lymphoma survivors treated with infradiaphragmatic radiotherapy (IRT) and/or procarbazine have an increased risk of developing colorectal cancer. We investigated the cost-effectiveness of colorectal cancer surveillance in Dutch Hodgkin lymphoma survivors to determine the optimal surveillance strategy for different Hodgkin lymphoma subgroups.
METHODS
The Microsimulation Screening Analysis-Colon model was adjusted to reflect colorectal cancer and other-cause mortality risk in Hodgkin lymphoma survivors. Ninety colorectal cancer surveillance strategies were evaluated varying in starting and stopping age, interval, and modality [colonoscopy, fecal immunochemical test (FIT, OC-Sensor; cutoffs: 10/20/47 μg Hb/g feces), and multi-target stool DNA test (Cologuard)]. Analyses were also stratified per primary treatment (IRT and procarbazine or procarbazine without IRT). Colorectal cancer deaths averted (compared with no surveillance) and incremental cost-effectiveness ratios (ICER) were primary outcomes. The optimal surveillance strategy was identified assuming a willingness-to-pay threshold of €20,000 per life-years gained (LYG).
RESULTS
Overall, the optimal surveillance strategy was annual FIT (47 μg) from age 45 to 70 years, which might avert 70% of colorectal cancer deaths in Hodgkin lymphoma survivors (compared with no surveillance; ICER:€18,000/LYG). The optimal surveillance strategy in Hodgkin lymphoma survivors treated with procarbazine without IRT was biennial FIT (47 μg) from age 45 to 70 years (colorectal cancer mortality averted 56%; ICER:€15,000/LYG), and when treated with IRT and procarbazine, annual FIT (47 μg) surveillance from age 40 to 70 was most cost-effective (colorectal cancer mortality averted 75%; ICER:€13,000/LYG).
CONCLUSIONS
Colorectal cancer surveillance in Hodgkin lymphoma survivors is cost-effective and should commence earlier than screening occurs in population screening programs. For all subgroups, FIT surveillance was the most cost-effective strategy.
IMPACT
Colorectal cancer surveillance should be implemented in Hodgkin lymphoma survivors.

Review
The human population may be exposed to potentially leukemogenic agents, either in the form of drugs and food additives or as environmental contaminants and pollutants. However, in spite of the large number and diversity of these chemicals, only a few have been implicated as human leukemogens. One such agent is benzene, a known bone marrow depressant. A number of case reports have associated chronic exposure to this agent with the development of acute leukemia, as have several epidemiologic surveys. Treatment with various antitumor agents, including procarbazine, melphalan, thio-TEPA, chlorambucil, and cyclophosphamide, has also been associated with the development of acute leukemia. In addition, chloramphenicol and phenylbutazone have been implicated as human leukemogens, but the association between exposure to these two agents and acute leukemia appears at present to be weaker than it is for benzene and antitumor agent exposure. Despite such associations between exposure to chemicals and acute leukemia, several important problems exist with regard to implicating specific agents in the development of this neoplasm in man, including the paucity of animal models for chemically induced leukemia, and the frequent necessity to rely on single case reports or clusters of cases in which chemical exposures are associated with acute leukemia. Future efforts should be directed at performing properly designed and well executed epidemiologic studies, and at developing new in vitro and in vivo models for the study of this neoplasm.

Review
Hodgkin lymphoma is a rare lymphoid malignancy affecting ∼9,200 new patients in the United States annually. Progress in the management of this disease over the past 50 years has been remarkable and the prognosis of this malignancy has changed from a uniformly fatal process to one in which the vast majority of patients are expected to be cured. This remarkable progress has been due to the use of combination approaches incorporating chemotherapy and radiation therapy, and now more recently antibody-drug conjugates and immune checkpoint inhibitors. The goal for the future is to develop treatment combinations that successfully treat all patients and markedly decrease the long-term side effects.
