RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and sustenance to the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Interest in complementary and alternative medicine (CAM) has grown exponentially in the past decade, fueled by Internet marketing, dissatisfaction with mainstream medicine, and a desire for patients to be actively involved in their health care. There is a large discordance between physician estimates and reported prevalence of CAM use. Many patients do not disclose their practices mainly because they believe CAM falls outside the rubric of conventional medicine or because physicians do not ask. Concern about drug interactions and adverse effects are compounded by a lack of Food and Drug Administration regulation. Physicians need to be informed about CAM and be attuned to the psychosocial needs of patients.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and sustenance to the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Nebulous language, distrust, and dogma confound spiritual aspects of cancer care. However, existential well being is an important determinant of quality of life: finding meaning and purpose make suffering more tolerable. The case presented is of a patient who experienced "losing God" as a Hodgkin's disease survivor with metastatic prostate cancer and severe coronary artery disease. His caregivers were able to provide the sense of community in which he could re-establish his faith. Health care providers do not have to be religious in order to help patients to deal with a spiritual crisis. The clinical skills of compassion need to be deployed to diagnose and respond to spiritual suffering. Acknowledging and addressing anger or guilt, common sources of suffering, are essential to adjustment. Simply being there for the patient and being open to their hurt can help resolve their spiritual crisis, a responsibility that is shared by the whole health care team.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and sustenance to the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Caring for colleagues who develop cancer is a privilege woven with an extra dimension-caregiver-patient issues. As well as stretching the usual need for a supportive relationship, when one of the health care team develops cancer it particularly provokes concerns about our own mortality. The case is presented of a well-known physician who developed a second cancer and has been cared for at the MGH Cancer Center Staff discuss her care as it has been effected by her status as a colleague. They perceived unique barriers to optimal care such as assumptions about the patient's level of medical knowledge, and technical, informational, emotional, and hierarchical issues that may obstruct the development of a trusting relationship between caregivers and the physician/patient. Emotional stress may prevent the sharing of an accurate prognosis. In the case under consideration, the patient had a frank and open attitude to her cancer yet her caregivers were concerned about continual breeches of patient confidentiality. Despite the many potential problems inherent when the caregiver becomes the patient, this case discussion was a poignant reminder of the unique challenges of every experience with cancer and the weighty privilege of being involved with patient care.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and sustenance to the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Medical errors are difficult to discuss. Significant medical errors occur in approximately 3% of hospitalizations. Two-thirds are preventable. Despite an entrenched belief that doctors should be infallible, errors are inevitable. Dr. Wendy Levinson of the University of Chicago facilitated a discussion of the impact medical errors have on staff. Staff broke into small groups to share their personal experience and then discussed common themes: the sense of shame and guilt, the punitive culture, guidelines for disclosure to patients and colleagues, and changes in medical practice that can prevent future mistakes. Auditing and improving systems has led to considerable improvements in the field of aviation safety. However, in medicine people are more important than the process. While we should never cease to aim for the very best in delivered care, we must acknowledge how prone we all are to mistakes and that we can learn from and prevent errors. Openly sharing experiences in a confidential setting, such as the Schwartz Rounds, helps defuse feelings of guilt and challenges the culture of shame and isolation that often surrounds medical errors.

RESUMO

PURPOSE: Curative up-front regimens for non-Hodgkin's lymphomas contain doxorubicin, vincristine, and cyclophosphamide, whereas salvage regimens generally contain non-cross-resistant agents. We hypothesized that up-front agents may be highly effective for salvage and developed an infusional regimen based on in vitro evidence of increased efficacy. PATIENTS AND METHODS: A prospective phase II study of etoposide, vincristine, and doxorubicin over 96 hours with bolus cyclophosphamide and oral prednisone (EPOCH) was performed in 131 patients with relapsed or resistant lymphoma. RESULTS: Seventy-nine percent of patients had aggressive histologies, 46% were considered high risk by the International Prognostic Index, and 34% had resistant disease. Eighty-eight percent of patients had received at least four of the agents in EPOCH, and 94% had received doxorubicin. In 125 assessable patients, 29 (24%) achieved complete responses and 60 (50%) achieved partial responses. Among 42 patients with resistant disease, 57% responded, and in 28 patients with relapsed aggressive de novo lymphomas, 89% responded with 54% complete responses. With a median follow-up of 76 months, the overall and event-free survivals (EFS) were 17.5 and 7 months, respectively. In 33 patients with sensitive aggressive disease who did not receive stem-cell transplantation, EFS was 19% at 36 months. Toxicity was primarily hematologic, with an 18% incidence of febrile neutropenia. No clinically significant cardiac toxicity was observed, despite no maximum cumulative doxorubicin dose. CONCLUSION: EPOCH is highly effective in patients who had previously received most/all of the same drugs and produces durable remissions in curable subtypes. Salvage regimens need not contain non-cross-resistant agents, and infusional schedules may partially reverse drug resistance and reduce toxicity.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. Psychosocial issues profoundly affect patients with cancer. Of the many complexities that make up the psychosocial dynamic, perhaps the medical profession is most uncomfortable with sexuality. Many elements of sexual behavior remain high-profile taboos. A number of diseases and treatments significantly affect sexual function. Male and female sexuality were discussed in two separate rounds with an emphasis on how to begin a dialogue about sexuality without jeopardizing other aspects of the relationship with patients. Three cases were presented. A patient with prostate cancer considering treatment options for early-stage disease and two patients with gynecologic malignancies; one with a colostomy following cytoreductive surgery for ovarian cancer and the other with a failed vaginal reconstruction for recurrent squamous cell carcinoma of the vagina. Staff discussed the wide diversity of response to sexual dysfunction and the difficulties that patients face. A sensitive and informed approach to discussing sexuality can provide effective support. The elements of successful dialogue are presented in the PLISSIT model.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. This case is of a woman with a personal, and a strong family history of breast cancer, who considered genetic testing for mutations in the BRCA1 and BRCA2 genes. The details of the case have been altered to protect the patient's anonymity. The patient was very anxious and there was disagreement between her healthcare providers about the potential benefits of genetic testing. The discussion of the case focused on several controversial issues, particularly the ownership of genetic information, and who is responsible for disseminating information to the family members at risk. The difficulties in communicating risk, providing emotional support and coping with the continuing uncertainties about screening and intervention are reviewed with an overview of the molecular biology, inheritance, and epidemiology of the BRCA1 and BRCA2 genes.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded the Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The case presented is of a young man dying of recurrent epithelioid hemangioendothelioma, distressed with stridor and severe pain, whose poorly controlled symptoms were successfully treated with an infusion of propofol, titrated to provide effective comfort in the last few hours of the patient's life. The tenet of double effect, which allows aggressive treatment of suffering in spite of foreseeable but unintended consequences, is reviewed. The patient's parents were invited and contributed to the Rounds, providing compelling testimony to the power of the presence of clinicians at the time of death and the importance of open communication about difficult ethical issues.

RESUMO

In an attempt to define the molecular changes associated with the paclitaxel-resistant phenotype in human cancer, a paclitaxel-resistant ovarian cancer cell line, SKOV-3TR, was established through stepwise selection in increasing paclitaxel concentrations. SKOV-3TR was cross- resistant to doxorubicin and vincristine and overexpressed multidrug resistance gene 1 but not multidrug resistance associated protein. SKOV-3TR and the paclitaxel-sensitive SKOV-3 parent line were characterized using human cDNA array technology that examined expression of a wide variety of genes involved in cell growth, signal transduction, cell death, and immune function. cDNA probes from reverse transcribed mRNAs of both paclitaxel-resistant and parent cells were compared to identify genes differentially expressed in the paclitaxel-resistant cells. Of 588 different human cDNA transcripts compared, 6 genes were found to be markedly decreased, and 12 genes increased in the resistant subline. Northern analysis and/or reverse transcription-PCR confirmed that 12 of these 18 genes were over- or underexpressed in SKOV-3TR. In addition, at least eight of the genes were found differentially expressed in several other paclitaxel- and/or doxorubicin-resistant cell lines, both those with increased multidrug resistance expression and those without. Included in the set of overexpressed genes were the cytokines/chemokines interleukin 6, interleukin 8, and monocyte chemotactic protein 1. ELISA assays confirm that mRNA overexpression of these cytokine/chemokines was associated with the increased secretion of these molecules in the tissue culture supernatant. Evaluation of supernatants from an expanded collection of paclitaxel- and Adriamycin-resistant cell lines demonstrated that all of the resistant lines had significant overexpression of at least one cytokine/chemokine as compared with their drug-sensitive parent line. The overexpression of these cytokines seemed to be stable and associated with a drug-resistant phenotype with only a modest induction of cytokine expression in the parent line with short-term paclitaxel exposure. These findings suggest that the development of paclitaxel resistance is accompanied by multiple changes in gene expression including stable alterations in selective chemokine and cytokine expression. The role these associated genetic changes have in the drug-resistant phenotype is discussed.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery, which provides hope to the patient, support to caregivers, and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The following case of an HIV-positive woman who was diagnosed with cervical cancer during a twin pregnancy was discussed at the May, 1999 Schwartz Center Rounds. The patient was in drug rehabilitation having been dependent on crack cocaine, with a past history of syphilis and gonorrhea. She was single and her other children were in foster care. Initially she was suspicious and non-compliant. A plan was negotiated to biopsy the cervical lesion after cesarean section and with confirmation of malignancy she underwent radical surgery and subsequently radiotherapy. Despite the almost insurmountable social and educational distance between her and her caregivers, they managed to bond and facilitate care. Although there were compromises with which staff were uncomfortable, the relationship was maintained and continues.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The following case of a woman who developed lymphoma was discussed at the July and August, 1997 Schwartz Center Rounds. There were considerable delays and uncertainties in the diagnosis, which was followed by an unpredictably chaotic clinical course. Although she had made it clear to her doctor that she did not want "heroic measures," she had unexpectedly rallied so many times that her son and her husband wanted her doctors to do everything possible to keep her alive, including the performance of cardiopulmonary resuscitation (CPR). The clinical benefit of CPR in the event of cardiac arrest in those with cancer is discussed, as are do not resuscitate (DNR) orders, living wills, and healthcare proxies. In addition, the issues that surround DNR status, including who should discuss DNR status with a patient, and how and when it should be discussed, are reviewed. Staff raised concerns about the effect of discussing DNR status on the doctor-patient relationship, and wondered whether writing DNR orders adversely affect the care of patients.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum during which caregivers discuss a specific cancer patient, reflect on the important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from their fellow staff members. In this article, the case presentation and verbatim dialogue from the rounds are discussed with an emphasis on staff psychosocial issues. The case presented was of a 32-year-old man, who developed small cell osteosarcoma and was treated at MGH. He died after undergoing multiple courses of relatively ineffective chemotherapy. The case is made all the more poignant because of the pleasures, hopes and stresses of having a child late in the course of his illness. Staff identified closely, both with him and his family, and their concern for him brought joy and meaning to their work, yet this complicated their ability to deal with his impending death. They felt that his unwillingness to admit defeat prevented them from saying goodbye to someone whom they loved and admired. Despite this, staff recognized that, ultimately, the patient's emotional needs and wishes had to be respected as a first priority and that constructive closure can be worked toward, if not achieved. In such situations, it is vital to have a colleague support system and a forum for discussion of such issues in order to defuse distress and reassure staff that they are doing all that can be done as professionals and caregivers.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process.

The case presented was of a 31-year-old man who developed adenocarcinoma of the lung with painful bone metastases. His tumor was unresponsive to treatment and he subsequently committed suicide by shooting himself. The verbatim and subsequent discussion raised a number of issues. Staff were devastated by the violent way that he ended his life. They questioned whether more could have been done to prevent this outcome, yet acknowledged that it mirrored the way he had lived, and were able to discuss the values by which we live and die. Some, but not all, felt that the patient had the right to choose how and when to end his life.

RESUMO

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a non-profit organization dedicated to supporting and advancing compassionate health care delivery which provides hope to the patient, support to caregivers, and encourages the healing process. The center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The September 1999 Schwartz Center Rounds addressed the growing attention around the phase I trial of Endostatin. Endostatin represents a new treatment paradigm. It is an anti-angiogenic protein, an endogenous fragment of collagen XVIII. In an attempt to ensure a fair allocation of a very limited number of treatment slots in this classical phase I trial, a lottery was established. More than 1,400 patients enrolled within two days of the lottery, all vying for three places in the first cohort. Two contrasting cases are presented, each a potentially eligible patient. The discussion focuses on the dilemma presented by patients desperate for an unproven treatment and the responsibility of staff to explain and support without compounding the hype or suffocating the hope.

RESUMO

Advances in the understanding of normal and malignant cell biology are allowing the development of biologically targeted drugs directed at specific differences between host and tumor. The array of potential new targets is vast, but drugs currently in development are targeted at cell-cycle regulators, growth factors and their receptors, signal transduction intermediates, angiogenesis, and the mechanisms that mediate apoptosis and DNA repair. Recent results raise the possibility that novel biologically targeted agents, perhaps in combination with traditional cytotoxic agents, may finally cure cancer. However, the development of a biologically targeted drug raises unique challenges in the design of clinical trials to demonstrate its efficacy, and despite the promising preclinical data that exist for most of the agents in development, the clinical trial remains the critical, final step across the bridge from basic research to clinical application. In this review, we discuss some of the challenges in the clinical development of biologically targeted agents and the implications for clinical trial design.

RESUMO

Recent insights into the molecular mechanisms of cancer have indicated that a variety of fundamental cellular processes are dysregulated in malignant cells. These processes include cell cycle control, signal transduction pathways, apoptosis, telomere stability, angiogenesis, and interactions with the extracellular matrix. Remarkable advances in molecular genetics, enzymology, and medicinal chemistry have permitted the design of compounds that modulate some of these processes with specificity that was unimaginable a decade ago. As these novel, biologically targeted compounds enter the clinic, they will require a strategy for clinical evaluation and development different from that used commonly for cytotoxic antineoplastic agents. This review examines the development of cancer drugs directed against angiogenesis, metastasis, signal transduction, telomerase, and molecular message (antisense), outlines strategies for the clinical testing of agents directed at these processes, and contrasts these efforts with traditional approaches to cancer drug testing.
