Patterns of recurrence following curative resection of adenocarcinoma of the colon and rectum

This study explores the patterns of recurrence after “curative” operation for colorectal cancer. For an 11‐year period, 1960–1971, 281 evaiuable patients were resected at the Peter Bent Brigham Hospital. Crude five‐year survival in these patients was 49%, but only 10% of those with recurrence lived five years. A total of 69 patients relapsed during their lifetime and 34 additional patients were found to have metastases at death. The initial site of metastases was regional in 23 patients (33%) and distant in 32 (46%). Simultaneous regional and distant metastases were found in 13 (19%) for a total of 65% of patients having initial distant metastases. Approximate recurrence rates by site were: 30% for sigmoid and rectum, 20% for right colon, and 10% for transverse and left colon. Tumor size was a significant determinant of recurrence but did not select for regional or distant sites. Recurrence by Astler‐Coller modification of the Dukes‐Kirklin classification revealed 10% for A + B1, 33% for B2, 35% for C1, and 50% for C2. More than half of the patients with distant metastases (18/32) had solely hepatic metastases yet the total incidence of liver metastases as the initial site was only 8% of the total. In general, the site of the primary cancer was the most important determinant of the type of recurrence; the stage and site of the primary tumor were most predictive for eventual relapse.

Survival of Patients Undergoing Chronic Hemodialysis and Renal Transplantation

Abstract Over an eight-year period 172 patients received an allograft from a living, related donor, 112 received cadaveric transplants, and 125 were placed on home dialysis. In a period of three years, 287 patients passed through our center dialysis program. Analysis of survival curves shows that patient survival was significantly better in recipients of transplants from living, related donors and in dialysis patients than in those receiving a cadaver graft. One-year patient survival rates for recipients of parental, sibling and cadaver allografts were 84.2, 89.5 and 68.7 per cent respectively. Survival rates at one and two years for home-dialysis patients were 88.5 and 77.8 per cent, and similar values for center patients were 92.9 and 86.1 per cent. These probabilities should be considered in the choice of which form of therapy to employ in a given patient, and illustrate the need for continued investigation into the prevention of allograft rejection and cadaver-recipient selection, (N Engl J Med 288:86...

Immunologic Rejection of Human Cancer Transplanted with a Renal Allograft

Abstract Metastatic carcinoma of the bronchus, inadvertently transferred to a patient when a kidney was transplanted from a cadaveric source, underwent immunologic rejection in the new host. This metastatic focus in and around the transplanted kidney did not appear until 18 months after the allograft was placed. When immunosuppressive therapy was discontinued, the previously functioning kidney was promptly rejected whereas tumor growth did not appear to be altered. After removal of the kidney, however, the residual cancer disappeared. The patient received a second kidney transplant nine months after removal of the first. There has been no evidence of further metastatic cancer despite resumption of a full program of immunosuppression.

Long-term hepatic arterial infusion of 5-fluorodeoxyuridine for liver metastases using an implantable infusion pump.

Twenty-one patients with liver metastases of various histologies (predominantly colorectal carcinoma) underwent Infusaid pump implantation for long-term hepatic arterial 5-fluorodeoxyuridine (5-FUdR) infusion. Patients received 5-FUdR infusion on a 2-wk cycle alternating with a 2-wk saline--heparin infusion. A dosage of 0.2-0.3 mg/kg/day (average 0.23 mg/kg/day) was infused for a cumulative 5-FUdR administration of 1940 days. Six patients (29%) responded to therapy (five colorectal, one carcinoid); median response duration was 6 mo. Median survival for the treated group was 17 mo from diagnosis of liver metastases and 13 mo from pump implantation. Median survival among the six responding patients was 15 mo from diagnosis of liver metastases and 11 mo from pump implantation. Comparison of survival from the diagnosis of liver metastases of the treated group to ten patients found ineligible for the study by virtue of extrahepatic metastases revealed no significant difference in median (18 mo for ineligible group) or overall survival. However, median survival for the treated group after pump implantation (13 mo) was significantly better than the median survival of the ineligible group after evaluation for this study (4 mo). Toxicities of therapy included fatigue, anorexia, nausea, vomiting, toxic hepatitis, epigastric pain, and diarrhea. No patients died of toxicity, but six patients required hospitalization for management of pain or vomiting. No serious technical complications developed in any patient except separation of the infusion catheter at its junction with the pump in one patient, necessitating pump replacement for continuation of therapy. These survival data suggest identification of new anticancer agents for hepatic arterial infusion.

Patterns of failure after surgical cure of large liver tumors: A change in the proximate cause of death and a need for effective systemic adjuvant therapy☆☆☆

During a period of 7 years, we have aggressively treated liver tumors whether primary or metastatic. Our experience after 43 curative major liver resections has shown an excellent overall survival: 34 of 43 patients still alive a median of 12 months after liver resection (patient ages ranged from 21 to 85 years, median 57 years). Nineteen patients underwent right hepatic lobectomy, 9 trisegmentectomy, 5 left hepatic lobectomy, 5 extended left hepatic lobectomy, 4 right lobectomy plus left lobe wedge resection, and 1 patient underwent a major hilar wedge resection. Two patients died from sepsis and hepatic failure on or before the 60th postoperative day. One patient with no evidence of recurrent colorectal cancer was lost to follow-up after 2.5 years. One patient died without cancer 12 months after left hepatic lobectomy for colon cancer metastases. Cumulative survival for the entire series and for patients after resection of colorectal cancer metastases was the same: 1 year survival 90 percent; 2 year survival 75 percent, and 3 year survival 65 percent. Seventeen of 30 patients remain disease-free after resection of liver metastases. Of the 13 who had recurrence, 8 are still alive. Ten recurrences were outside of the residual liver (predominantly multiple pulmonary metastases). One recurrence was in the right hemidiaphragm, and only three were in the residual or regenerated liver. Serial carcinoembryonic antigen analysis was the best indicator of recurrence in these 13 patients, 12 of whom were asymptomatic. These data confirm that major liver resection can be performed with minimum postoperative mortality (4.7 percent in this series). More importantly, the majority of patients were cured of their liver metastases. The next goal should be the initiation of adjuvant systemic therapy trials after liver resection in such patients.

Listeriosis in immunosuppressed patients: A cluster of eight cases

Bactermia due to listeria monocytogenes developed in eight patients who were receiving immunosuppresive medications during a 15 month period at one hospital. Seven survived. Meningitis was documented in only the four who received kidney transplants. Their neurologic signs were minimal, indicating a need to treat any immunosuppressed patient with Listeria bacteremia for meningitis. During this period the incidence of Listeria bactermia in immunosuppressed patients greatly exceeded that previously observed in this hospital or reported elsewhere, but the incidence of infection with other opportunistic agents was not increased. As with previously decreased listeria outbreaks in nonimmunosuppressed patients, no source or mechanism of spread could be identified. Thus, disease due to L. monocytogenes may occur focally among immunosuppressed populations, a pattern which also appears to be emerging for other opportunistic agents. A patients exposure to different opportunistic agents may be as important as the kind of immunosuppressive therapy he recieves in determining which opportunistic infection he will acquire or even whether any infection will occur.

Renal transplantation: a twenty-five year experience.

Boston has played a significant role in the development of renal transplantation. In Boston was performed the first successful isograft between identical twins (1954) the first successful allograft between fraternal twins (1959) and the first successful allograft from a cadaveric donor (1962). An immunosuppressive drug was also described in Boston by hematologists Schwartz and Dameschek (1959) and modified for renal transplantation in dogs (1961) and used for the first time in a human recipient in March 1962. By 1965 renal transplantation had become a clinical reality. Three hundred and ninety-eight of 589 recipients (68%) since 1950 are still alive, a remarkable figure considering that it includes all the earliest experimental transplants. One hundred and ninety-five of 295 (68%) with living-related donor transplants still have functioning allografts; 104/265 (39%) with cadaveric donor transplants have functioning grafts currently. Since 1968 transplants from living-related donors have an 80% one year survival whereas cadaveric donor transplants have approximately a 50% one year survival. Seventy-nine per cent of all one year survivors have had excellent psycho-social rehabilitation.

Effects of parathyroidectomy and kidney transplantation on renal osteodystrophy

Abstract Four patients with azotemic hyperparathyroidism have been studied and treated at the Peter Bent Brigham Hospital. Subtotal parathyroidectomy was performed in all of these cases, and two patients received renal homografts as well. These patients comprise a unique group in the total clinical entity of hyperparathyroidism in whom neck exploration is often justified despite persistently normal values for serum calcium concentration and urine calcium excretion. If diffuse chief cell hyperplasia is found, about seven eighths of the parathyroid tissue should be removed; severe tetany, although transient, must be anticipated in the early postoperative period. The proper combination of subtotal parathyroidectomy and renal homotransplantation in these specific patients with renal osteodystrophy may provide striking rehabilitation. Data have been presented to support the contention that subtotal parathyroidectomy should precede renal transplantation whenever possible.

Abdominal pain in neutropenic cancer patients.

A review of 58 patients with malignancies (age range, 14–73 years), who required surgical consultation for acute abdominal pain in the setting of neutropenia (granulocyte count < 1000/mm3) after chemotherapy was conducted. Ninety percent had fevers greater than 37.83C, 30% had diarrhea or melena, and 25% had diminished bowel sounds. Five of the 29 patients (17%) with localized pain had surgical intervention; 3 of 29 patients (10%) with generalized pain underwent operations (2 for x‐ray findings). All eight of these surgically treated patients survived to leave the hospital. Eighteen of the 29 patients with generalized pain were believed to have a similar syndrome of diarrhea (occasionally heme positive) and diffuse abdominal tenderness (some with peritoneal signs and distension), which was termed „neutropenic enteropathy”︁. Eleven of these 18 patients had their symptoms resolve with antibiotic therapy, aggressive fluid replacement, and a return of their granulocyte count to normal. The other seven died of pneumonia (two), unknown causes (one), and diffuse enterocolitis throughout the intestinal tract (four documented at autopsy). The overall 30‐day mortality rate in this series was 34%. Several factors correlated significantly with mortality: hypotension at the onset of pain (80% mortality), bacteremia (63% mortality), and fungemia (100% mortality). Absolute leukocyte count and absolute platelet count did not correlate with mortality. This study reaffirms that patients with neutropenic enteropathy are best treated conservatively. Patients with surgically correctable disease were identified by specific focal findings on examination or x‐ray.
