ABSTRACT

Purpose@#The female sex is reported to have a higher risk of adverse events (AEs) from cytotoxic chemotherapy. Few studies examined the sex differences in AEs and their impact on the use of medical services during adjuvant chemotherapy. This sub-study aimed to compare the incidence of any grade and grade ≥ 3 AEs, healthcare utilization, chemotherapy completion rate, and dose intensity according to sex. @*Materials and Methods@#This is a sub-study of a multicenter cohort conducted in Korea that evaluated the impact of healthcare reimbursement on AE evaluation in patients who received adjuvant chemotherapy between September 2013 and December 2016 at four hospitals in Korea. @*Results@#A total of 1,170 patients with colorectal, gastric, or non–small cell lung cancer were included in the study. Female patients were younger, had fewer comorbidities, and experienced less postoperative weight loss of > 10%. Females had significantly higher rates of any grade AEs including nausea, abdominal pain, stomatitis, vomiting, and neutropenia, and experienced more grade ≥ 3 neutropenia, nausea, and vomiting. The dose intensity of chemotherapy was significantly lower in females, and they also experienced more frequent dose reduction after the first cycle. Moreover, female patients receiving platinum-containing regimens had significantly higher rates of unscheduled outpatient visits. @*Conclusion@#Our study found that females experienced a higher incidence of multiple any-grade AEs and severe neutropenia, nausea, and vomiting, across various cancer types, leading to more frequent dose reductions. Physicians should be aware of sex differences in AEs for chemotherapy decisions.

ABSTRACT

Purpose@#This study aimed to confirm the decision-making patterns for life-sustaining treatment (LST) and analyze medical service utilization changes after enforcement of the Life-Sustaining Treatment Decision-Making Act. @*Materials and Methods@#Of 1,237 patients who completed legal forms for life-sustaining treatment (hereafter called the LST form) at three academic hospitals and died at the same institutions, 1,018 cancer patients were included. Medical service utilization and costs were analyzed using claims data. @*Results@#The median time to death from completion of the LST form was three days (range, 0 to 248 days). Of these, 517 people died within two days of completing the document, and 36.1% of all patients prepared the LST form themselves. The frequency of use of the intensive care unit, continuous renal replacement therapy, and mechanical ventilation was significantly higher when the families filled out the form without knowing the patient’s intention. In the top 10% of the medical expense groups, the decision-makers for LST were family members rather than patients (28% patients vs. 32% family members who knew and 40% family members who did not know the patient’s intention). @*Conclusion@#The cancer patient’s own decision-making rather than the family’s decision was associated with earlier decision-making, less use of some critical treatments (except chemotherapy) and expensive evaluations, and a trend toward lower medical costs.

ABSTRACT

Purpose@#At the end of life, communication is a key factor for good care. However, in clinical practice, it is difficult to adequately discuss end-of-life care. In order to understand and analyze how decision-making related to life-sustaining treatment (LST) is performed, the shared decision-making (SDM) behaviors of physicians were investigated. @*Methods@#A questionnaire was designed after reviewing the literature on attitudes toward SDM or decision-making related to LST. A final item was added after consulting experts. The survey was completed by internal medicine residents and hematologists/medical oncologists who treat terminal cancer patients. @*Results@#In total, 202 respondents completed the questionnaire, and 88.6% said that the decision to continue or end LST is usually a result of SDM since they believed that sufficient explanation is provided to patients and caregivers, patients and caregivers make their own decisions according to their values, and there is sufficient time for patients and caregivers to make a decision. Expected satisfaction with the decisionmaking process was the highest for caregivers (57.4%), followed by physicians (49.5%) and patients (41.1%). In total, 38.1% of respondents said that SDM was adequately practiced when making decisions related to LST. The most common reason for inadequate SDM was time pressure (89.6%). @*Conclusion@#Although most physicians answered that they practiced SDM when making decisions regarding LST, satisfactory SDM is rarely practiced in the clinical field. A model for the proper implementation of SDM is needed, and additional studies must be conducted to develop an SDM model in collaboration with other academic organizations.

ABSTRACT

Acromegaly is a slowly progressing condition resulting from excess growth hormone (GH), generally caused by a GH-secreting pituitary adenoma. Cancer is the third most common cause of mortality in patients with acromegaly, and insulin-like growth factor 1 (IGF-1) is known to influence tumor formation by increasing cell proliferation and inhibiting apoptosis. Multiple myeloma (MM) is a plasma cell neoplasm, and previous studies have suggested the possible role of IGF-1 in its development of MM. However, no cases of acromegaly accompanied with MM have been reported in Asia to date. We here report the case of a 58-year-old woman with acromegaly accompanied with MM who presented with longstanding acromegalic manifestations resulting from a GH-secreting pituitary adenoma and also exhibited anemia, a reversed albumin/globulin ratio, and plasmacytosis on bone marrow examination. Because IGF-1 has been suggested to play an important role in the development and progression of MM, the patient promptly underwent surgical removal of the pituitary adenoma via a transsphenoidal approach. Since there is currently no consensus on therapeutic guidelines and suggested prognosis for MM with acromegaly, long-term follow-up of such cases is needed.

ABSTRACT

Primary lymphoma of the urinary bladder is rare, comprising 0.2% of extranodal lymphomas. The predominant subtype of mucosa-associated lymphoid tissue (MALT) is extranodal marginal zone lymphoma. We report a case of MALT lymphoma of the urinary bladder in a 53-year-old female patient presenting with a five-year history of persistent hematuria and urinary frequency. A cystoscopy revealed multiple nodular lesions at the posterior wall and trigone of the bladder. The tissue obtained by cold-cup biopsy revealed lymphoid infiltration consistent with low-grade MALT lymphoma. Image studies revealed that the tumor originated from the urinary bladder and there was no evidence of metastases. The patient was positive for a rapid urease test. Because of the relationship between gastric MALT lymphoma and Helicobacter pylori, the patient was treated with antibiotics to eradicate Helicobacter pylori. The lymphoma subsequently disappeared and the patient has remained in persistent complete remission for eight years.

ABSTRACT

BACKGROUND: Multicentric Castleman's disease (CD) is commonly associated with poor prognosis, and well-known prognostic factors are scarce. We performed a retrospective analysis to define the clinical features and prognostic factors for patients with multicentric CD. METHODS: Between 1990 and 2013, 32 patients with multicentric CD were identified from the database of the Asan Medical Center, Seoul, Korea. Clinicopathologic data were collected by reviewing the medical records. With the exclusion of 4 patients because of unknown human immunodeficiency virus infection status, 28 human immunodeficiency virus-negative patients with multicentric CD were included in this analysis. RESULTS: Most of the patients were male (76%) and had a median age of 54 years. Hyaline vascular variant was the most common subtype (N=11, 39%). Hepatosplenomegaly (61%), fever (39%), edema (29%), and ascites (18%) were the most frequently reported symptoms and signs at diagnosis. With a median follow-up of 67 months, the 5-year overall survival (OS) was 77%. Patients with extravascular fluid accumulation (i.e., peripheral edema, ascites, and/or pleural effusions) were significantly associated with a poor survival rate (5-year OS, 94% vs. 56%; P=0.04). The extent of disease involvement was also a significant prognostic factor (5-year OS, 91% for involvement on a single side vs. 73% on both sides of the diaphragm; P=0.03). Other clinicopathologic factors were not significantly associated with patient survival. CONCLUSION: Our findings suggest that the hyaline vascular variant is not a rare subtype of multicentric CD. Extravascular fluid accumulation and disseminated disease involvement seem to be significant prognostic factors.
