Long-Term Follow-up of Survival in Hodgkin's Lymphoma

To the Editor: In 1992, the Cancer and Leukemia Group B (CALGB) reported the results of a prospective three-group randomized trial involving 359 patients with Hodgkin's lymphoma. This trial compared the following regimens: doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for 6 to 8 months, mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) for 6 to 8 months, and MOPP alternating with ABVD for 12 months.1 The trial was limited to patients with advanced disease (clinical stages III and IV). No radiotherapy was administered. The results, published in the Journal in 1992, indicated an event-free survival advantage of ABVD over MOPP but no . . .

Thoracoscopic Lobectomy: A Safe and Effective Strategy for Patients Receiving Induction Therapy for Non-Small Cell Lung Cancer

Thoracoscopic lobectomy is an accepted oncologic approach for early stage non-small cell lung cancer (NSCLC). We conducted a retrospective study of patients who underwent lobectomy after induction therapy to determine the feasibility of thoracoscopic lobectomy compared with conventional thoracotomy lobectomy. The outcomes of 97 consecutive patients with NSCLC who received induction therapy followed by lobectomy from 1996 to 2005 were reviewed. Outcome variables analyzed included complete resection, chest tube duration, length of hospitalization, 30-day mortality, hemorrhage, pneumonia, respiratory failure, and other major complications. The Student t test and chi2 or RxC contingency tables were used to compare continuous and categoric variables, respectively. Lobectomy was performed by thoracotomy in 85 patients and thoracoscopically in 12 patients (1 conversion), with complete resection in all patients. All patients received induction chemotherapy, and 74 (76%) received induction radiotherapy as well: 66 of 85 (78%) in the thoracotomy group and 8 of 12 (67%) in the thoracoscopy group. The overall median survival was 2.3 years, with no difference between the groups. Patients undergoing a thoracoscopic lobectomy had a shorter median hospital stay (3.5 vs 5 days, p = 0.0024) and chest tube duration (2 vs 4 days, p < 0.001). There were no significant differences in 30-day mortality, hemorrhage, pneumonia, or respiratory failure. Thoracoscopic lobectomy is a feasible approach for selected patients undergoing resection after induction therapy, and is associated with shorter hospital stay and chest tube duration. Long-term follow-up of survival will determine the role of thoracoscopic lobectomy in the management of patients after induction therapy.

Long‐term survival for a cohort of adults with cerebral palsy

The aim of this study was to investigate long-term survival and examine causes of death in adult patients with cerebral palsy (CP). A 1940-1950 birth cohort based on paediatric case referral allows for long-term survival follow-up. Survival is analyzed by birth characteristics and severity of disability from age 20 years (and age 2y for a subset of the data). Survival outcome compared with that expected in the general population based on English life tables. The main cohort consisted of 341 individuals, with 193 males and 148 females. Conditional on surviving to age 20 years, almost 85% of the cohort survived to age 50 years (a comparable estimate for the general population is 96%). Very few deaths were attributed to CP for those people dying over 20 years of age. Females survived better than males. However, females faced a greater increase in risk relative to the general population than did males. We conclude that survival outlook is good though lower than in the general population. The relative risk of death compared with the UK population decreases with age, although it shows some indication of rising again after age 50 years. Many more deaths were caused by diseases of the respiratory system among those dying in their 20s and 30s than would be expected in the general population. Many fewer deaths than expected in this age group are caused by injuries and accidents. For those people who die in their 40s and 50s, an increase in deaths due to diseases of the circulatory system and neoplasms is observed. More deaths than expected in this age group are due to diseases of the nervous system.

Surviving intensive care: a report from the 2002 Brussels Roundtable.

The traditional goal of intensive care has been to decrease short-term mortality. While worthy, this goal fails to address the issue of what it means to survive intensive care. Key questions include whether intensive care survivors have optimal long-term outcomes and whether ICU care decisions would change if we knew more about these outcomes. The 2002 Brussels Roundtable, "Surviving Intensive care", highlighted these issues, summarizing the available evidence on natural history and risk factors for critical illness and outlining future directions for care and research. Critical illness is associated with a wide array of serious and concerning long-term sequelae that interfere with optimal patient-centered outcomes. Although traditional short-term outcomes, such as hospital mortality, remain extremely important, they are not likely to be adequate surrogates for subsequent patient-centered outcomes. As such, it is important to focus specifically on how critical illness and intensive care affects a patient's and relatives' long-term health and well-being. There are a large number of potential pre-, intra-, and post-ICU factors that may improve or worsen these outcomes, and these factors are subjects for future research. In addition, future clinical trials of ICU therapies should include long-term follow-up of survival, quality of life, morbidity, functional status, and costs of care. Follow-up ought to be for at least six months. The SF-36 and EuroQOL EQ-5D are the best-suited instruments for measuring quality of life in multicenter critical care trials though further methodologic research and instrument design is encouraged. There are also opportunities today to improve care. Key to taking advantage of such opportunities is the need for a global awareness of critical illness as an entity that begins and ends outside the ICU 'box'. Specific interventions that show promise for improving care include ICU discharge screening tools and ICU follow-up clinics.

Long-term follow-up of survival of liver transplant recipients with familial amyloid polyneuropathy (Portuguese type).

Portuguese type familial amyloid polyneuropathy is a dominantly inherited neuropathic amyloidosis caused by a mutant transthyretin (TTR). Because TTR is produced mainly by the liver, liver transplantation (LT) abolishes production of the amyloidogenic variant TTR. To date, the procedure appears to halt the progress of the disease. However, long-term outcome is unknown. The aim of the present study is to evaluate the survival of our initial group of unselected liver transplant recipients with FAP. Seventy patients, 51 transplant recipients and a control group of 19 nontransplantation patients, with disease onset before the age of 55 years were included on the study. Transplant recipients were divided into two categories: (1) early series, with patients followed up for 5 years or longer, and (2) new series, with patients followed up for 1 to 5 years. Nonparametric statistical methods were used. Binary regression analyses were performed by stepwise logistic regression and Cox proportional hazard regression. Survival analysis was performed using Kaplan-Meier analysis, the Cox-Mantel test. Survival analyses and Cox proportional hazard regression analysis were performed from disease onset, not from LT. Significantly decreased survival was noted for transplant recipients with a modified body mass index (mBMI) less than 600 compared with the control group (P < .05). A significant difference in survival also was observed between transplant recipients with an mBMI greater than 600 at the time of LT compared with those with an mBMI less than 600 (P < .02). mBMI and age at LT had a significant impact on survival; whereas late deaths were related to age at LT, early deaths were related to mBMI. The cumulative 10-year survival rate after disease onset was 94% in the new series, with one early death (< 6 months) after LT, compared with a 78% survival rate and eight early deaths in the early series (P = .1).
