Sequential chemotherapeutic regimens, primarily used in the treatment of hematopoietic
malignancies
, and employing ara-C as a basic antineoplastic agent induce mucosal alterations in the entire gastrointestinal tract. These are characterized by surface and glandular epithelial atypia, immaturity, and necrosis. Glandular regeneration is characteristically delayed leading to a state of intestinal aproliferative cytopenia. Other toxic intestinal changes include telangiectasia of blood vessels and the formation of intramural hematomas. Intestinal infections develop frequently and are complicated by peritonitis, liver abscesses, pneumatosis cystoides in testinalis and
sepsis
. These intestinal lesions are accompanied by a predictable clinical syndrome which begins concomitantly with ara-C infusions and is characterized by diarrhea, ileus, abdominal pain, hematemesis and melena, severe hypokalemia, hypocalcemia and a protein-losing enteropathy. Additional toxic manifestations induced by ara-C include transient weight gains, fever elevations and severe bone marrow depression. The genesis of the intestinal lesions is linked to the three day dose schedule of ara-C infusions which insures both arrest of the cycling intestinal cells in the S-phase and a high cytotoxic index. The severity of these lesions is markedly augmented by prior treatment with ara-C and cyclophosphamide which causes synchronization and probable recruitment of intestinal stem cells, respectively.

Alpha-hemolytic Streptococci were associated with 29 episodes of
sepsis
(12 polymicrobial) in 27 patients with
cancer
during a nine year period. Only two patients had dental manipulation prior to the onset of
sepsis
, but each had received chemotherapy and 75% were granulocytopenic (PMN less than 500/mm3) at the time of the infection. None of the patients developed bacterial endocarditis. Unlike the normal host in whom a transient bacteria with alpha-hemolytic Streptococci may occur following dental extraction or periodontal procedures, the
cancer
patient is at risk for more clinically significant
sepsis
. This risk is probably related to the presence of chemotherapy-induced oral mucusitis and granulocytopenia, and our results suggests that isolation of alpha-hemolytic Streptococci in febrile
cancer
patients should not be dismissed as a contaminent.

In a review of 2,616 consecutive autopsies done at the University of Kentucky Medical Center over a 12-year period, 46 patients with complete postmortem examinations had tissue-verified candidiasis in two distinct patterns, with Candida albicans being most frequently cultured. Superficial candidiasis involving only lining surfaces was observed in 21 patients (46%). Usually, it complicated other lethal problems such as
malignancy
and bacterial
sepsis
. Nineteen of these patients (95%) had received antibiotics. No vessel invasion or deep organ involvement was evident in this group. The other pattern of candidiasis was a deep or systemic variety recognized in the remaining 25 patients (54%). It was characterized by deep parenchymal organ lesions usually involving the brain (52%), heart (48%), and kidney (80%), but any tissue seemed susceptible. Vessel invasion was seen in 8 patients (32%); intravenous lines were used in 13 (52%); and major operations were done in 16 (64%). All these patients were hospitalized for either benign or malignant conditions and were treated for bacterial
sepsis
with antibiotics for seven days or more. This investigation indicates that candidiasis occurs when the host's environment is altered primarily by antibiotic therapy. Candida then can colonize lining surfaces and from there could invade adjacent vessels and disseminate throughout the body.

An unusual syndrome of hepatosplenomegaly and fever followed by rapid deterioration and death has been described in 38 children from 21 families. Pancytopenia, liver dysfunction, and bleeding developed prior to death from hemorrhage,
sepsis
, or lymphocytic meningitis. This report reviews the literature and adds a set of twins to the reported cases.

Intravenous hyperalimentation was utilized to support nutritionally 23 malnourished patients with major head and neck tumors during surgical treatment, radiotherapy, or the convalescent period. Fifteen patients were treated during the perioperative period and 12 survived. Six patients received convalescent nutritional support successfully 4 to 24 months following operation or radiation treatment. Two patients received treatment with hyperalimentation throughout a protracted course of radiation therapy. Weight gain, wound healing, and recovery were achieved in all but 3 patients. Subclavian vein thrombosis occurred in 1 patient, and catheter-related
sepsis
occurred in 2 patients. Otherwise, hyperalimentation was safe and efficacious in the debilitated patients. These patients may now become acceptable risks for surgical treatment or radiation therapy by nutritional repletion with intravenous hyperalimentation.

Bleeding and infection are the usual proximate causes of morbidity and mortality in patients with hematologic
malignancy
and many solid tumors. The most important cause of bleeding is thrombocytopenia. The use of immunologically matched platelets has rendered this complication less frequent. Host defenses against infection are often compromised unavoidably as a function of the primary disease and its therapy. However, it is important to note that many infections are caused by hospital-acquired organisms; a significant number of infections can be avoided with meticulous attention to possible breaches of the host barriers against invasion. Diagnosis and treatment of infection in the altered host are urgent and demanding, since the median survival with inappropriate therapy of bacterial
sepsis
is less than 3 days. Newer diagnostic techniques, such as the gallium scan, are helpful, as are antimicrobial combinations used empirically. Experimental approaches to the prevention of infection include antibacterial vaccines, the use of laminar air-flow isolation, and transplantation of bone marrow. Experimental approaches to the therapy of infection include leukocyte transfusion and the use of transfer factor. A discussion of supportive care must also include consideration of the psychosocial concomitants of the
cancer
process, particularly those factors in the doctor-patient relationship which promote anxiety in the physician to the end that his support of the patient is not effective.

Methyl-CCNU, a compound with marked antitumor activity against the solid Lewis lung tumor in mice, was submitted to a preclinical pharmacologic evaluation. The toxicity of a single iv infusion was tested in 37 beagle dogs and 21 rhesus monkeys. The minimum lethal dose (LD) in dogs was 14 mg/kg and five of six dogs died within 7-10 days after treatment from hematopoietic toxicity with neutropenia, lymphopenia, anemia, and concomitant
sepsis
. Metaplasia of the intestinal epithelium also occurred. Thrombocytopenia was not observed. Dogs treated with 9.27-1.56 mg/kg exhibited reversible neutropenia and lymphopenia but survived without severe morbidity or histopathologic lesions. In monkeys, interstitial nephritis was the treatment-limiting toxicity and three of six monkeys treated with 45 or 30 mg/kg died, became moribund, or exhibited severe renal histopathologic lesions. One monkey treated with 45 mg/kg had degeneration of the testes. Survivors exhibited reversible toxicity and no histopathologic lesions. Treatment with doses as low as 7.5 mg/kg caused reversible neutropenia, lymphopenia, and anemia. The largest nontoxic dose for a single iv infusion was 3.12 mg/kg (62.40 mg/m2) for the dog and 3.75 mg/kg (45 mg/m2) for the monkey. These and earlier observations showed that methyl-CCNU had approximately one third the toxicity of CCNU. Methyl-CCNU also did not cause the delayed hepatic toxicity which is characteristic of CCNU treatment in the dog.

Diagnosis of disseminated intravascular coagulation (DIC) was made in 64 cases (16.2%) among a total of 395 autopsy cases. There were 31 men and 33 women. Their ages ranged from 31 to 91 years (mean 76.3). Underlying diseases were mainly
malignancy
and
sepsis
. Fresh cardiac lesions were found in 40 cases (62.5%). Coronary thrombosis was found in 13 cases (20.3%) and myocardial necrosis in 24 cases (37.5%), with acute myocardial infarction in 9 and focal necrosis in 15. Nonbacterial thrombotic endocarditis was found in 17 cases (26.6%), mural thrombi in 11 (17.2%), and bleeding of the heart in 11 (17.2%). Platelet count, fibrinogen and euglobulin lysis time were not correlated with myocardial necrosis nor coronary thrombosis. Increase of fibrin degradation products correlated with the presence of coronary thrombosis with or without myocardial necrosis. DIC was found with a high incidence in the aged, and many of them were complicated with fresh cardiac lesions. Development of acute myocardial infarction depends on the small thrombi in the severe stenosis of the main coronary arteries or on the multiple microthrombi in the peripheral coronary branches.

The clinical course, operative treatment, and results of 129 patients with carcinoma obstructing the left side of the colon were reviewed. There were 64 cases of incomplete obstruction, all secondary to primary adenocarcinoma of the colon. Sixty-five patients had complete obstruction; 37 of these had primary adenocarcinoma of the colon, and the rest,
cancer
from other primary sites, largely the genitourinary tract. The operations involving colostomy only or colostomy as part of a staged resection resulted in high operative mortality and low long-term survival, in addition to a high rate of postoperative
sepsis
. Results of operations involving primary resection of obstructing tumor were superior in all the above factors studied.

Host starvation is a common accompaniment to the presence of
cancer
. Diminished intake is a major contributor to this starvation and does not require that the oropharynx or gastrointestinal tract be the primary site. There is suggestive evidence that the normal adaptive mechanisms of the nontumor-bearing host to starvation that result in body protein conservation are not functioning in the tumor-bearing host. Cancer cachexia has some similarity to the metabolic disturbances of host metabolism that are seen in major injury or
sepsis
. The growing tumor shows little respect for normal constraints of host tissue growth. With the widespread availability of methods of total parenteral nutrition, the interrelationship of nutrition and host-tumor growth assumes greater importance.
