BackgroundStudies indicate that the incidence of young women diagnosed with colorectal cancer is rising, thus there is an increasing number of female colorectal cancer survivors of premenopausal and child-bearing age. Adjuvant FOLFOX (5-fluorouracil, leucovorin, and oxaliplatin) chemotherapy is the most widely used standard treatment for stage III and high-risk stage II colon cancer. We evaluated the incidence of FOLFOX-induced amenorrhea in women age 50 and younger treated with adjuvant therapy for colorectal cancer.Patients and MethodsA search of pharmacy records identified 119 women age 50 or younger who received adjuvant FOLFOX chemotherapy at Memorial Sloan-Kettering for stage II or III colorectal cancer from January 2002 and January 2011. Eligible patients were mailed an anonymous questionnaire. The returned surveys were reviewed and the results tallied.ResultsSeventy-three patients returned the questionnaire. Twenty-four patients were excluded from analysis: 19 were treated with pelvic radiotherapy, 2 patients had undergone bilateral oophorectomy, 2 had a hysterectomy, and 1 stopped menstruating before diagnosis. Forty-nine patient responses were analyzed. In total, 41% (n = 20) experienced amenorrhea during chemotherapy. Sixteen percent had persistent amenorrhea 1 year after completion of chemotherapy. The incidence of amenorrhea during chemotherapy trended higher in patients aged older than 40 compared with patients aged 40 and younger (59% vs. 31% [P = .075]). There was no statistically significant difference in persistent amenorrhea between the 2 age groups (24% vs. 13%; P = .42).ConclusionIn this retrospective series, there appears to be a trend toward FOLFOX induced amenorrhea during chemotherapy increasing with age. Twenty-four percent of women older than the age of 40 were found to have persistent amenorrhea after FOLFOX therapy. Because of the small sample size, the study is underpowered to detect a statistically significant difference between older and younger patients. Prospective studies are planned to further characterize the effect of FOLFOX on early menopause and fertility. 相似文献

The introduction of androgen blockade therapy using luteinising hormone-releasing hormone (LHRH)/gonadotropin-releasing hormone analogues alone or in combination with non-steroidal antiandrogens has a major impact in both survival and quality of life of patients with locally advanced and metastatic prostate cancer. The effect of LHRH agonists is based on the continuous binding to the LHRH receptor (LHRH-R) on the gonadotrope cells of the pituitary, which although initially stimulate LH release, consequently downregulates the LHRH-R, thereby suppressing serum LH, testosterone levels and 5alpha-dihydrotestosterone levels. Because this initial surge of LH and testosterone can cause adverse consequences in these patients (the so-called flare-up symptoms), immediate inhibition of LH release and testosterone production is desirable and this can be achieved with the use of the LHRH antagonists. In addition, there exist data to support a direct anticancer effect of LHRH antagonists on prostate cancer cells. This review summarises the potential clinical use of the LHRH antagonists in prostate cancer patients. 相似文献

A rare case of disseminated Mycobacterium avium complex with colitis in a renal transplant recipient
Marinela Ingilizova Shara Epstein Dong Heun Lee Neal Patel Shraddha Patel Babariya Ricardo Morgenstern Nikolay Popnikolov Dagan Coppock 《Transplant infectious disease》2019,21(1)
Mycobacterium avium complex (MAC) colitis is a rare complication of immunosuppression in solid organ transplant (SOT) recipients. Here, we describe a case of disseminated MAC infection with colitis following renal transplantation. Despite common pathways of immunosuppression, SOT recipients and human immunodeficiency virus (HIV)‐infected patients differ in their typical presentations of MAC infection. Intestinal infections have been more commonly reported in HIV‐infected patients than in SOT recipients. The explanation for this difference may be related to HIV's targeted effects on the CD4+ T‐cell reservoir in gut‐associated lymphoid tissue. 相似文献

The differentiation of a stem cell is dependent on the environmental cues that it receives and can be modulated by the expression of different master regulators or by secreted factors or inducers. The use of genetically modified stem cells to express the required factors can direct differentiation along the requisite pathway. This approach to the engineering of stem cells is important, as control of the pluripotentiality of stem cells is necessary in order to avoid unwanted growth, migration or differentiation to nontarget tissues. The authors provide an overview of the stem cell engineering field, highlighting challenges and solutions, and focusing on recent developments in therapeutic applications in areas such as autoimmunity, CNS lesions, bone and joint diseases, cancer and myocardial infarction. 相似文献

The intracelomic route for in utero hematopoietic stem cell transplantation was evaluated in preimmune fetal sheep and the engraftment characteristics were defined. Twelve twin ovine fetuses (gestational age: 40-45 days) received intracelomic transplants of human CD3-depleted (50 x 10(6) per lamb) or CD34-selected (1-2 x 10(5) per lamb) cord blood hematopoietic stem cells. Engraftment was evaluated from cell suspensions of the liver, spleen, bone marrow, and thymus by flow cytometry, cloning assays, and polymerase chain reaction (PCR) analyses of human beta2-microglobulin. Four fetuses (33%) aborted shortly after intracelomic transplantation and were not evaluable for engraftment. Engraftment was detected in four fetuses obtained from cesarean delivery on day 70 after transplantation of CD3-depleted cord blood cells. The degrees of engraftment in these four fetuses ranged from 6%-22% in the different organs (as revealed by antigenic analysis of human CD45 with flow cytometry). Three fetuses obtained after cesarean section at 102 (no. 435184) and 105 (no. 915293, no. 037568) days and one fetus delivered at term that received CD34-selected cord blood cells had human engraftment with 10%, 32%, 20%, and 10% CD45(+) cells in bone marrow, respectively. In six of eight fetuses evaluable for human engraftment, chimerism was confirmed by PCR analysis for human beta2-microglobulin, which also identified human cells in brain, spinal cord, heart, lung, and skeletal muscle. This preliminary study indicates that intracelomic transplantation of human hematopoietic stem cells in fetal lambs is feasible and effective in terms of hematopoietic engraftment. 相似文献
