Background: Multidrug chemotherapy for Ewing sarcoma can lead to severe myelosuppression. We proposed two clinical questions (CQ): CQ #1, "Does primary prophylaxis with G-CSF benefit chemotherapy for Ewing sarcoma?" and CQ #2, "Does G-CSF-based intensified chemotherapy improve Ewing sarcoma treatment outcomes?".

Methods: A comprehensive literature search was conducted in PubMed, Cochrane Library, and Ichushi web databases, including English and Japanese articles published from 1990 to 2019.

Introduction: Chemotherapy for breast cancer can cause neutropenia, increasing the risk of febrile neutropenia (FN) and serious infections. The use of granulocyte colony-stimulating factors (G-CSF) as primary prophylaxis has been explored to mitigate these risks. To evaluate the efficacy and safety of primary G-CSF prophylaxis in patients with invasive breast cancer undergoing chemotherapy.

Article Synopsis
  • G-CSF is a supportive treatment used to prevent severe complications from chemotherapy in patients with non-round cell soft tissue sarcomas (NRC-STS), with two key clinical questions raised about its effectiveness.
  • A literature review found a limited number of studies that addressed these questions, resulting in only a few articles being included for analysis.
  • The conclusion suggests that there is insufficient scientific evidence to confirm the benefits of G-CSF prophylaxis in improving treatment outcomes for NRC-STS, indicating the need for further research.

Article Synopsis
  • Relapsed or refractory acute myeloid leukemia (AML) has poor outcomes, and the impact of granulocyte colony-stimulating factor (G-CSF) combined with chemotherapy is still debated.
  • A systematic literature review and meta-analysis were conducted, assessing 11 studies, which suggested that G-CSF priming did not significantly improve response rates or overall survival for AML patients, although there was a slight trend towards lower relapse rates.
  • Certain groups, particularly those with intermediate cytogenetic risk and those receiving high-dose cytarabine, showed prolonged overall survival with G-CSF priming, indicating the need for further research to find the most suitable patients for this treatment approach.*

Background: Febrile neutropenia represents a critical oncologic emergency, and its management is pivotal in cancer therapy. In several guidelines, the use of granulocyte colony-stimulating factor (G-CSF) in patients with chemotherapy-induced febrile neutropenia is not routinely recommended except in high-risk cases. The Japan Society of Clinical Oncology has updated its clinical practice guidelines for the use of G-CSF, incorporating a systematic review to address this clinical question.

Article Synopsis
  • Granulocyte colony-stimulating factor (G-CSF) is used to prevent febrile neutropenia (FN) in cancer patients, with two types available in Japan: long-lasting PEG G-CSF and short-term non-PEG G-CSF.
  • A systematic review of studies found that PEG G-CSF significantly reduces the incidence of FN compared to non-PEG G-CSF, based on a thorough analysis of 23 articles.
  • The study concludes that a single dose of PEG G-CSF is preferred for primary prevention of FN, as it shows stronger evidence compared to multiple doses of non-PEG G-CSF.

Article Synopsis
  • Granulocyte colony-stimulating factor (G-CSF) is used to reduce the risk of neutropenia and infections during cancer chemotherapy, but its effectiveness for digestive system tumors is still uncertain.
  • A systematic review was conducted to evaluate the effectiveness of G-CSF as primary prophylaxis and its impact on the intensity of chemotherapy for various digestive system tumors.
  • The findings indicated that while G-CSF's use in colorectal cancer chemotherapy is inappropriate, there wasn't enough data to make strong recommendations for other types of digestive cancers.

Background: Docetaxel (DTX) is commonly used as a primary chemotherapy, and cabazitaxel (CBZ) has shown efficacy in patients who are DTX resistant. Primary prophylactic granulocyte colony stimulating factor (G-CSF) therapy is currently used with CBZ treatment in routine clinical care in Japan.

Methods: In this study, we performed a systematic review following the Minds guidelines to investigate the effectiveness and safety of primary prophylaxis with G-CSF during chemotherapy for prostate cancer and to construct G-CSF guidelines for primary prophylaxis use during chemotherapy.

Article Synopsis
  • The review examines the optimal timing for administering prophylactic pegylated granulocyte colony-stimulating factor (G-CSF) during cancer chemotherapy, focusing mainly on Day 2 versus Days 3-5.
  • Out of 300 studies initially reviewed, only four met the criteria, suggesting a potential increase in febrile neutropenia when G-CSF is given on Days 3-5 compared to Day 2, but no significant differences in overall survival or infection-related mortality were found.
  • The findings indicate weak recommendations for both timing options and emphasize the need for more research to make clearer guidelines for pegylated G-CSF administration.

Granulocyte colony-stimulating factor (G-CSF) decreases the incidence, duration, and severity of febrile neutropenia (FN); however, dose reduction or withdrawal is often preferred in the management of adverse events in the treatment of urothelial cancer. It is also important to maintain therapeutic intensity in order to control disease progression and thereby relieve symptoms, such as hematuria, infection, bleeding, and pain, as well as to prolong the survival. In this clinical question, we compared treatment with primary prophylactic administration of G-CSF to maintain therapeutic intensity with conventional standard therapy without G-CSF and examined the benefits and risks as major outcomes.

Although granulocyte colony-stimulating factor (G-CSF) reduces the incidence, duration, and severity of neutropenia, its prophylactic use for acute myeloid leukemia (AML) remains controversial due to a theoretically increased risk of relapse. The present study investigated the effects of G-CSF as primary prophylaxis for AML with remission induction therapy. A detailed literature search for related studies was performed using PubMed, Ichushi-Web, and the Cochrane Library.

Article Synopsis
  • G-CSF is used to prevent febrile neutropenia (FN) in cancer patients, but there's limited evidence on its effectiveness specifically for lung cancer.
  • Studies on non-small-cell lung cancer (NSCLC) showed some potential benefits in reducing FN incidence, while small-cell lung cancer (SCLC) showed no significant impact.
  • Overall, there is not enough data to make strong recommendations for G-CSF use in lung cancer, but it may be considered for certain NSCLC patients on specific therapies.

What Is Known And Objective: Oxaliplatin (L-OHP) is an antineoplastic agent that frequently causes vascular pain. However, the risk factors for vascular pain are unclear, and prevention methods have not been established. We retrospectively investigated patients who were treated with L-OHP to examine the influence of patient characteristics and concomitant analgesic use on the incidence of vascular pain.

A requirement, which students must satisfy, for a diploma at the Showa University School of Pharmacy is the ability to "plan, practice, and assess pharmacotherapy". To continuously assess the ability of students to meet this requirement and to provide patients with proper pharmacotherapy during student clinical rotations, we formulated the "Rubric assessment for pharmacotherapy" and evaluated its usefulness in tutorial learning classes. Clinical pharmacy faculty members created the rubric based on the Subjective, Objective, Assessment, and Plan (SOAP) note guidelines of the university.
