Paramedic rapid sequence intubation in patients with non-traumatic coma.

INTRODUCTION: Pre-hospital intubation by paramedics is widely used in comatose patients prior to transportation to hospital, but the optimal technique for intubation is uncertain. One approach is paramedic rapid sequence intubation (RSI), which may improve outcomes in adult patients with traumatic brain injury. However, many patients present to emergency medical services with coma of non-traumatic cause and the role of paramedic RSI in these patients remains uncertain. METHODS: The electronic Victorian Ambulance Clinical Information System was searched for the term 'suxamethonium' between 2008 and 2011. We reviewed the patient care records and included patients with suspected non-traumatic coma who were treated and transported by road-based paramedics. Demographics, intubation conditions, vital signs (before and after drug administration) and complications were recorded. Younger patients (<60 years) were compared with older patients. RESULTS: There were 1152 paramedic RSI attempts of which 551 were for non-traumatic coma. The success rate for intubation was 97.5%. There was a significant drop in blood pressure in younger patients (<60 years) with the mean systolic blood pressure decreasing by 16 mm Hg (95% CI 11 to 21). In older patients, the systolic blood pressure also decreased significantly by 20 mm Hg (95% CI 17 to 24). Four patients suffered brief cardiac arrest during pre-hospital care, all of whom were successfully resuscitated and transported to hospital. CONCLUSIONS: Paramedic RSI in patients with non-traumatic coma has a high procedural success rate. Further studies are required to determine whether this procedure improves outcomes.

Paediatric hanging associated out of hospital cardiac arrest in Melbourne, Australia: characteristics and outcomes.

INTRODUCTION: Hanging is a rare but devastating cause of out of hospital cardiac arrest (OHCA). The characteristics and outcomes of hanging associated OHCA in the paediatric age group are described. METHODS: The Victorian Ambulance Cardiac Arrest Registry was searched for patients aged less than 18 years where the precipitant cause of OHCA was hanging. Results were cross checked with the coronial database. RESULTS: During the years 2000-2009, there were 680 paediatric cardiac arrests of which 53 (7.8%) were precipitated by hanging with an incidence of 4.4 per million paediatric patients (<18 years) per year. Median age was 16 (IQR 14-17) years and 58.5% were males. Five were unintentional hangings; median age 3 (IQR 2-4) years. The youngest deliberate hanging associated OHCA was aged 10 years. Most hangings occurred in a house (85%) and bystander cardiopulmonary resuscitation (CPR) was performed in 30%. Asystole was the most common initial cardiac arrest rhythm seen in 50 cases (94%) while three patients had pulseless electrical activity. The emergency medical services (EMS) attempted resuscitation in 18 patients (34%), inserting an endotracheal tube in 13 patients. The majority (n=41) were not transported; seven patients were transported with return of spontaneous circulation (ROSC) and five patients were transported with ongoing CPR. Victims who had bystander CPR were more likely to have EMS attempted resuscitation (p<0.001). Only patients who had received bystander CPR achieved ROSC (p<0.001). Three patients survived to hospital discharge; two survivors suffered severe neurological injury (Cerebral Performance Category Scale 3-4). CONCLUSION: Non-intentional hanging is rare but deliberate hanging with suicidal intent represents a significant proportion of OHCAs in patients under 18 years of age. A focus on prevention is key, as outcomes are poor, with survivors likely to suffer a severe neurological insult.

Diabetes mellitus affects response to neoadjuvant chemoradiotherapy in the management of rectal cancer.

INTRODUCTION: Although diabetic patients with rectal cancer have poorer outcomes than their nondiabetic counterparts, few studies have looked at diabetics' response to therapy as an explanation for this disparity. This study compares the neoadjuvant chemoradiotherapy (CRT) response in diabetic and nondiabetic patients with locally advanced rectal cancers. METHODS: This is a single-institution, retrospective review of rectal cancer patients who received CRT followed by resection from 1995 to 2006. Pretreatment tumor-node-metastasis (TNM) staging was determined using endorectal ultrasound, computed tomography (CT) scan, and magnetic resonance imaging (MRI); post-treatment staging was determined by pathological review. RESULTS: 110 patients were included; seventeen had diabetes and 93 were nondiabetics. Pretreatment staging was similar in both groups. Sixteen of the diabetics (94%) completed CRT compared to 92% (86/93) of the nondiabetics. Tumor downstaging rates were similar in the two groups (53% in diabetics, 52% in nondiabetics). Nondiabetic patients had a higher rate of nodal downstaging although not statistically significant (67% versus 27%, P = 0.80). While none of the diabetics patients achieved a pathologic complete response (pCR), 23% (21/93) of the nondiabetics did (P = 0.039). Local progression rates were higher in the diabetic group (24% versus 5%, P = 0.046). CONCLUSION: Our study shows that neoadjuvant chemoradiotherapy in rectal cancer is less effective in diabetic patients than in nondiabetics. While minimal differences are found in the rate of downstaging, the rate of achieving a complete pathologic response was significantly higher in nondiabetic patients, and in fact was not seen in any of our diabetic patients. This may explain the poorer outcomes seen in diabetic patients with rectal cancer.

Drug interactions in palliative care.

PURPOSE: This review of drug interactions in palliative care examines the relevant literature in this area and summarizes the information on interactions of drugs, nutrients, and natural products that are used in the palliative care setting. Particular emphasis is placed on describing the newer information on the cytochrome P450 (CYP) system and the interactions of opioids, antidepressants, and the antitussive, dextromethorphan. METHODS: We performed a search of the MEDLINE database of the time period from 1966 until April 1998, using medical subject headings such as the names of selective serotonin reuptake inhibitors and other relevant medications in palliative care. Literature reviewed included both human and animal articles as well as non-English literature. Bibliographies of these articles and the personal libraries of several palliative care specialists were reviewed. Software developed by The Medical Letter-The Drug Interaction Program was also used. RESULTS: Drug interactions can be categorized in several ways. Drug-drug interactions are the most well known and can be kinetic, dynamic, or pharmaceutical. Pharmacokinetic interactions can involve CYP 2D6, which acts on drugs such as codeine and is responsible for its conversion to morphine. Poor metabolizers, either genotypic or due to phenocopying, are at risk for undertreatment if not recognized. Pharmacodynamic interactions with dextromethorphan may produce serotonin syndrome. CONCLUSION: Drug interactions are important in palliative care as in other aspects of medicine. These interactions are similar to those seen in other areas of medical care but have significant consequences in pain management. Failure to recognize these interactions can lead to either overdosing or undertreatment.

Concurrent radiation therapy and chemotherapy followed by esophagectomy for localized esophageal carcinoma.

PURPOSE: A prospective study was performed to determine the outcome of patients with esophageal cancer who received preoperative radiation therapy and chemotherapy followed by esophagectomy, and to determine the role of preresection esophagogastroduodenoscopy (EGD) in predicting the patients in whom surgery could possibly be omitted, and the impact of surgery on survival. MATERIALS AND METHODS: Thirty-five patients with localized carcinoma of the esophagus received concurrent external-beam radiotherapy and chemotherapy followed by esophagectomy. Patients received 45 Gy in 25 fractions. Chemotherapy consisted of continuous infusion fluorouracil (5-FU; 1,000 mg/m2/d) on days 1 through 4 and 29 through 32 and cisplatin (100 mg/m2) on day 1. Patients underwent an Ivor-Lewis esophagectomy 18 to 33 days after completion of radiotherapy. RESULTS: Eighty percent of the patients had squamous cell carcinoma and 20% had adenocarcinoma. In addition, 51% had a pathologic complete response (CR). Twenty-two of the 35 underwent a preresection EGD before resection. Seventeen of the 22 (77%) had negative pathology from the preresection EGD, but seven of the 17 (41%) had residual tumor at surgery. The median survival and disease-free survival rates for all patients were 25.8 months and 32.8 months, respectively. Eighteen patients (51%) had no tumor at resection. The median survival for these patients was 36.8 months; the median disease-free survival time has not been reached. The median survival and disease-free survival rate for the patients with residual tumor in the surgical specimen were 12.9 months and 10.8 months, respectively. CONCLUSION: Preresection EGD is not reliable for determining the presence of residual disease or the patients in whom surgery could be omitted. Twenty-five percent of the patients with residual tumor in the resected surgical specimen were long-term survivors; this suggests a benefit from esophagectomy after concurrent radiotherapy and chemotherapy.

Phase I trial of twice-weekly gemcitabine and concurrent radiation in patients with advanced pancreatic cancer.

PURPOSE: To determine the maximum-tolerated dose, dose-limiting toxicities, and potential antitumor activity of twice-weekly gemcitabine and concurrent radiation in patients with locally advanced pancreatic cancer. PATIENTS AND METHODS: Nineteen patients with histologically confirmed adenocarcinoma of the pancreas were studied at the Wake Forest University Baptist Medical Center and the University of North Carolina at Chapel Hill. The initial dose of gemcitabine was 20 mg/m(2) by 30-minute intravenous infusion each Monday and Thursday for 5 weeks concurrent with 50.4 Gy of radiation to the pancreas. Gemcitabine doses were escalated in 20-mg/m(2) increments in successive cohorts of three to six additional patients until dose-limiting toxicity was observed. RESULTS: The dose-limiting toxicities at 60 mg/m(2) given twice-weekly were nausea/vomiting, neutropenia, and thrombocytopenia. Twice-weekly gemcitabine at a 40-mg/m(2) dose was well tolerated. Of the eight patients eligible for a minimum follow-up of 12 months, three remain alive, one of whom has no evidence of disease progression. CONCLUSION: A dose of twice-weekly gemcitabine at 40 mg/m(2) produced mild thrombocytopenia, neutropenia, nausea, and vomiting when delivered with concurrent radiation to the upper abdomen in patients with advanced pancreatic cancer. These data suggest this regimen is well tolerated and may possess significant activity. These data and other observations have resulted in a phase II Cancer and Leukemia Group B study to ascertain the efficacy of this treatment regimen in patients with locally advanced pancreatic cancer.

Acute, reversible left ventricular dysfunction in status asthmaticus.

Three cases of rapidly reversible severe myocardial depression are described in patients with status asthmaticus. Initial echocardiograms obtained within 1 day of hospital admission revealed global left ventricular hypokinesis with ejection fractions of 11 to 34%. Follow-up echocardiograms obtained only 3 to 8 days later revealed marked improvement of left ventricular function. Possible mechanisms responsible for the observed rapidly reversible myocardial depression and the clinical implications of this finding are discussed.

Oophoropexy and the management of Hodgkin's disease. A reevaluation of the risks and benefits.

Female patients with Hodgkin's disease who undergo staging laparotomy frequently have oophoropexy performed to preserve both fertility and hormone production. Because of recent changes in therapy favoring systemic chemotherapy rather than total nodal irradiation for patients with stage III Hodgkin's disease, the need for oophoropexy may be less than previously described. Thirty-nine women of childbearing age underwent laparotomy at the University of North Carolina, Chapel Hill, from 1970 to 1984. Twenty-seven patients underwent oophoropexy. Only three of these patients would have needed this procedure based on their subsequent therapy. Two patients required additional gynecologic surgery because of complications related to the oophoropexy. The success rate in preservation of menstrual function and fertility is also discussed. We review the previous experience with oophoropexy and suggest an alternative approach to the routine use of this procedure.

Soluble complement receptor type I limits damage during revascularization of ischemic myocardium.

BACKGROUND: This study was undertaken to determine whether suppression of complement activation with soluble human complement receptor type I reduces myocardial damage during the revascularization of ischemic myocardium. METHODS: In 20 pigs, the second and third diagonal coronary arteries were occluded for 90 minutes, followed by 45 minutes of cardioplegic arrest and 180 minutes of reperfusion. In 10 pigs, soluble human complement receptor type I (10 mg/kg) was infused over 30 minutes before the period of coronary occlusion; 10 other pigs received no soluble human complement receptor type I. Complement activation was measured by total hemolytic complement activity (expressed as a percentage of preischemic values). Ischemic damage was assessed by changes in myocardial tissue pH, wall motion scores (range, 4=normal to -1=dyskinesia), and infarct size (area of necrosis versus area at risk). RESULTS: After 180 minutes of reperfusion, hearts treated with soluble human complement receptor type I had significantly less complement activation than nontreated hearts (1.1%+/-0.09% versus 7.8%+/-0.04%, respectively; p < 0.002), less myocardial acidosis (-0.41+/-0.03 versus -0.72+/-0.03, respectively; p < 0.0001), higher wall motion scores (3.1+/-0.09 versus 1.67+/-0.16, respectively; p < 0.0001), and smaller infarct size (24.6%+/-2.0% versus 41%+/-1.3%, respectively; p < 0.0001). CONCLUSIONS: Complement inhibition with soluble human complement receptor type I significantly limits ischemic damage during the revascularization of acutely ischemic myocardium.

High tissue affinity angiotensin-converting enzyme inhibitors improve endothelial function and reduce infarct size.

BACKGROUND: Angiotensin-converting enzyme (ACE) inhibitors differ in their ability to inhibit tissue ACE. This study was, therefore, undertaken to determine whether high tissue affinity ACE inhibitors would improve endothelial function and thereby decrease tissue necrosis during ischemia. METHODS: In a porcine model, the second and third diagonal vessels were occluded for 90 minutes, followed by 45 minutes of cardioplegic arrest and 180 minutes of reperfusion. During the period of coronary occlusion, 10 pigs received enalaprilat (low affinity tissue ACE inhibitor), 0.05 mg/kg intravenously, 10 received quinaprilat (high affinity tissue ACE inhibitor), 10 mg intravenously, and 10 others received no ACE inhibitor. RESULTS: Wall motion scores (4, normal, to -1, dyskinesia) were higher in animals treated with ACE inhibitors (3.20+/-0.15 SE enalaprilat versus 3.08+/-0.23 quinaprilat versus 1.52+/-0.07 no ACE; both p < 0.0001 from no ACE). Endothelial-dependent relaxation to bradykinin was best preserved in the quinaprilat-treated hearts (32.1%+/-7.6% enalaprilat versus 65.8%+/-12.6% quinaprilat versus 30.6%+/-10.7% no ACE; p < 0.0001 from no ACE; p < 0.005 from enalaprilat). This was associated with a greater reduction in infarct size: area necrosis/area risk 24.3%+/-0.8% enalaprilat (p < 0.0001 from no ACE) versus 14.3%+/-3.2% quinaprilat (p < 0.0001 from no ACE; p < 0.005 from enalaprilat) versus 40.0%+/-1.7% no ACE. CONCLUSIONS: ACE inhibitors with higher affinity to tissue ACE result in better preservation of endothelial function and less tissue necrosis during coronary revascularization.

Induction chemoradiotherapy followed by esophagectomy in patients with carcinoma of the esophagus.

BACKGROUND: Induction chemoradiotherapy followed by esophagectomy may provide results superior to those of single-modality treatment in patients with esophageal cancer. The purpose of this study was to review our experience with this approach for esophageal cancer. METHODS: From 1988 to 1996, 166 consecutive patients with esophageal cancer were evaluated; 66 entered a protocol of chemotherapy (5-fluorouracil, cisplatin) concurrent with radiation (45 Gy) followed by esophagectomy. Fifty-four patients completed the protocol. RESULTS: Toxicity associated with induction chemoradiotherapy was minimal. The actuarial survival at 12, 24, and 36 months was 59%, 42%, and 32%, respectively. The pathologic complete response (pCR) rate was 41%, with 12-, 24-, and 36-month survivals of 77%, 50%, and 45%, whereas non-pCR patients had survivals of 46%, 35%, and 23%. The difference in survival between pCR and non-pCR patients was not significant (p = 0.13), but the difference in recurrence-free survival was significant (p = 0.007). CONCLUSIONS: This well-tolerated protocol resulted in a high pCR. Trimodality treatment for esophageal cancer may provide long-term survival in some patients regardless of their pCR status.

Heparin-bonded circuits decrease myocardial ischemic damage: an experimental study.

BACKGROUND: Heparin-bonded cardiopulmonary bypass circuits reduce complement activation, but their effect on myocardial function is unknown. This study was undertaken to determine whether heparin-bonded circuits reduce myocardial damage during acute surgical revascularization. METHODS: In 16 pigs, the second and third diagonal vessels were occluded with snares for 90 minutes followed by 45 minutes of cardioplegic arrest and 180 minutes of reperfusion with the snares released. During the period of coronary occlusion, all animals were placed on percutaneous bypass followed by standard cardiopulmonary bypass during the periods of cardioplegic arrest and reperfusion. In 8 pigs, heparin-bonded circuits were used, whereas 8 other pigs received nonbonded circuits. RESULTS: Animals treated with heparin-bonded circuits had the best preservation of wall motion scores (3.5 +/- 0.3 versus 2.3 +/- 0.2; 4 = normal to -1 = dyskinesis; p < 0.05), least tissue acidosis (change in pH = -0.31 +/- 0.02 versus -0.64 +/- 0.08; p < 0.05), smallest increase in lung H2O (1.7% +/- 0.7% versus 6.1% +/- .5%; p < 0.05), and the lowest area of necrosis/area of risk (20.3% +/- 2.2% versus 40.4% +/- 1.6%; p < 0.05). CONCLUSIONS: We conclude that heparin-bonded circuits significantly decrease myocardial ischemic damage during acute surgical revascularization.

Acute delta 9-tetrahydrocannabinol exposure alters Ca2+ ATPase activity in neuroendocrine and gonadal tissues in mice.

Acute administration of delta 9-tetrahydrocannabinol (THC) (50 mg/kg) at puberty (35-40 days) significantly (P less than 0.05) reduced Ca2+ ATPase activity in hypothalamic plasma membranes but increased, although not significantly, enzyme activity in hypothalamic tissue obtained from adult mice. In contrast, testicular Ca2+ ATPase activity was increased in pubertal THC-treated males, and significantly reduced in adults. Pituitary Ca2+ ATPase activity exhibited a dose-related decrease after acute THC administration at 0.5, 5 or 50 mg/kg, but there were no differential effects of age. Pituitary plasma membranes obtained from THC-treated males did not respond to in vitro exposure to luteinizing hormone releasing hormone (LHRH, 10(-7) M) with the marked reduction (approximately 40%) in Ca2+ ATPase activity observed in pituitaries from oil-treated controls. In addition, effects of THC appear specific for Ca2+ ATPase activity, since Mg2+ ATPase and Na+/K+ ATPase activities were not affected. These findings indicate that acute in vivo administration of THC influences Ca2+ membrane transport, in particular Ca2+ ATPase activity. These effects occur at each level of the hypothalamic-pituitary-gonadal (HPG) axis, are related to dose and developmental age at exposure, and also appear specific for Ca2+-dependent ATPase activity. Furthermore, THC exposure modulates pituitary sensitivity to LHRH receptor-mediated effects on Ca2+ ATPase activity. Therefore, effects on Ca2+ membrane transport may be involved in acute THC actions on hormonal activity at these HPG sites.

Methotrexate elimination in a patient with an orthotopic neobladder with and without a urethral catheter.

Placement of a urethral catheter has been recommended to ensure adequate methotrexate elimination in patients with a neobladder; however, the need for this and its impact on methotrexate elimination have not been determined. A 53-year-old man with a cecal continent urinary diversion received intravenous methotrexate 30 mg/m2 on two occasions, with and without urethral catheter drainage of the neobladder. Serum methotrexate concentrations declined at a rate that resulted in 24- and 48-hour values falling below the accepted toxic concentration threshold of 5-50 mumol/L, and 0.05 mumol/L, respectively. In this man, who received low-dose methotrexate, catheterization of the neobladder did not alter methotrexate elimination sufficiently to justify its cost, risk, and inconvenience.

Vomiting associated with pentostatin and pentostatin plus alpha-interferon: unique pattern and potential mechanisms.

Pentostatin (2'-deoxycoformycin) is a unique antineoplastic agent that has proven valuable in the treatment of a number of lymphoid malignancies. Dose-limiting toxicities observed in clinical trials include central nervous system (CNS) effects and acute renal failure. Information regarding the incidence, duration, and severity of nausea and vomiting from published reports is conflicting and insufficient to provide recommendations for optimal supportive measures. We report the results of a phase I study where pentostatin was associated with a 20% incidence of vomiting following courses one and two (pentostatin alone). The third course of pentostatin administered concurrently with alpha interferon resulted in a 29% incidence of vomiting and by course four had increased to 50%. Grade of severity was similarly increased, and nausea and vomiting was the dose-limiting toxicity in 6 of 15 patients. Forty-two percent of all episodes of vomiting were delayed in onset (onset 24 hr after drug administration) and in over 80% of cases persisted for greater than 48 hr in duration. Potential mechanisms that may account for these findings, as well as recommendations regarding antiemetic therapy are provided.

Cancer pain survey: patient-centered issues in control.

It is widely believed that patients' reluctance to report pain and adhere to treatment recommendations are significant barriers to cancer pain control. However, few investigators have examined barriers to cancer pain management from the cancer patient's perspective. Ambulatory patients with cancer who had experienced cancer-related pain in the previous month or were currently taking analgesics for cancer pain control were asked to participate in this study. Information regarding (a) pain assessment, (b) pain medication use, (c) concerns and barriers to compliance, (d) communication patterns regarding pain and pain control, and (e) demographics were collected during a 10-min structured interview. Approximately 20% of patients with a current cancer diagnosis who were approached reported that they had experienced pain or taken analgesic drugs during the preceding month. Eighty-eight percent of these patients ranked their pain as five or greater (scale, 0-10), and 81% reported impaired function due to pain. Major barriers to effective treatment included forgetfulness, the belief that pain should be tolerated, concerns about side effects, and fear and disdain of dependence, addiction, and tolerance. One-third of patients felt that their pain could not be better controlled than it currently was. Patients reported frequent communication regarding pain and pain control with physicians (52%), nurses (41%), and pharmacists (17%). The low pain prevalence, coupled with high pain intensity and associated dysfunction, appears to be a reflection of patient's unwillingness to report pain of mild to moderate intensity. In addition to previously recognized factors, stoicism and fatalism represent significant barriers to cancer pain control.

Adjuvant therapy of rectal cancer.

The treatment of rectal cancer has gradually evolved based on our knowledge of the failure patterns. Although results with surgery alone are good in patients with disease limited to the bowel wall and with no lymph node spread, surgery alone is less effective for more advanced disease. Treatment strategies that combine pelvic radiation therapy and 5-fluorouracil-based chemotherapy regimens have significantly improved local recurrence rates and overall survival results for patients with disease extending through the bowel wall or those with positive lymph nodes. Recent studies suggest that methyl CCNU can be dropped from chemotherapy regimens without loss of efficacy. Newer strategies being investigated include modulations of 5-fluorouracil with agents such as leucovorin and levamisole, possibly in combination, and continuous infusions of 5-fluorouracil.

The evaluation of cocaine-induced chest pain with acute myocardial perfusion imaging.

OBJECTIVE: To use myocardial perfusion imaging to determine the etiology of cocaine-induced chest pain in patients without ECG evidence of acute cardiac ischemia. METHODS: The authors conducted a prospective study of consecutive consenting patients aged 18-70 years with cocaine-induced chest pain who reported cocaine use within three days and presented with a chief complaint of chest pain occurring within three hours and lasting longer than 15 minutes with a normal or nondiagnostic ECG. Patients were excluded if they had a clear-cut noncardiac cause of chest pain, ECG evidence of acute cardiac ischemia, history of myocardial infarction, pregnancy, or lactation, required immediate hospitalization, or were unable to consent. Patients were injected with Tc-99m tetrofosmin and imaged. Perfusion scans were independently read by two nuclear radiologists. Clinicians blinded to scan results determined patient disposition. Patients with abnormal scans were asked to return for follow-up resting scans. RESULTS: Fourteen patients were enrolled. Twelve of the 14 patients had chest pain at the time of Tc-99m tetrofosmin injection. Ten of the 14 [(71%) 95% CI = 48% to 95%] scans were normal or within normal limits. Four of the 14 [(29%) 95% CI = 5% to 52%] were abnormal. Of the four patients with abnormal scans, two had follow-up scans that demonstrated an irreversible perfusion abnormality, and two who did not return for follow-up reported no subsequent hospitalizations for acute cardiac ischemia. CONCLUSION: Perfusion imaging did not demonstrate reversible ischemia in most patients (12/14, 86%) with cocaine-induced chest pain without ECG evidence of ischemia. These results suggest that cocaine-induced chest pain in most patients without ECG evidence of ischemia is not due to acute ischemia.

Chemoradiation for locally advanced squamous cell carcinoma of the head and neck for organ preservation and palliation.

OBJECTIVES: To measure the efficacy and toxic effects of our chemoradiotherapy regimen by means of response and survival in patients with advanced squamous cell carcinoma of the head and neck (HNSCC) for organ preservation in resectable disease or palliation in unresectable disease. DESIGN: All patients underwent evaluation by the multidisciplinary head and neck cancer team, with pathological diagnosis and staging. All patients underwent assessment for response to therapy using results of physical examination and radiologic imaging. Patients were followed up at 3-month intervals for a planned period of 5 years. SETTING: Academic center. PATIENTS: Thirty-eight previously untreated patients with newly diagnosed HNSCC were treated from June 1, 1996, through December 31, 1998, of whom 20 had resectable and 18 had unresectable tumors. INTERVENTION: Patients received intravenous cisplatin, 100 mg/m(2) for 1 hour on days 1 and 29; a 24-hour continuous infusion of fluorouracil, 1000 mg/m(2) on days 1 through 4 and 29 through 32; and radiation therapy, 150 rad twice daily for 12 days. The patients were given a 7- to 10-day break, and radiation therapy was restarted on day 29 for 12 additional days (total dose, 7200 rad). MAIN OUTCOME MEASURES: Complete, partial, and total response rates; disease-free survival; overall survival; and toxic effects. RESULTS: Toxic effects of treatment were moderately severe, including grades III to IV mucositis (89%), neutropenia (71%), and renal toxic effects (8%). In the 18 patients in the unresectable group, complete response in the 17 primary tumors and 15 cervical nodal metastases was achieved in 12 (71%) and 9 (60%), respectively; in the 20 patients undergoing organ preservation, complete response rates were 100% in the 23 primary tumors and 15 cervical nodal metastases. Complete response for all 38 patients was achieved in 31 (82%). In the unresectable group, the Kaplan-Meier relapse-free survival estimate is 56%, with follow-up from 29 to 45 months. In the organ preservation group, 75% of patients are alive without disease, and 8 have been followed up for 36 to 48 months. Of the 5 patients who have died, only 2 died of disease, with recurrences at 13.0 and 16.5 months. CONCLUSIONS: Chemoradiotherapy consisting of cisplatin, fluorouracil, and twice-daily external beam radiation is highly effective in achieving durable complete responses in patients with resectable HNSCC undergoing organ preservation and patients with unresectable HNSCC undergoing palliation. Toxic effects of this regimen were moderate to severe.

Skin reactions to radiotherapy--a spectrum resembling erythema multiforme: case report and review of the literature.

Eruptions resembling erythema multiforme associated with radiotherapy are rare. Although several case reports are cited in the older literature, only recently has this phenomenon been described in patients receiving external beam radiation therapy both with and without contributory concurrent medications. The eruption typically begins within the radiation port and then generalizes; it is usually self-limited, but serious and fatal outcomes are reported. We review the literature and report a case of an eruption resembling erythema multiforme associated with external beam irradiation and 5-fluorouracil.
