The authors conducted a retrospective analysis of 1178 patients with histologically proven invasive carcinoma of the uterine cervix treated with irradiation alone. The minimum follow‐up time was 3 years. The 10‐year actuarial pelvic failure rate in Stage IB was 6% for tumors less than 3 cm, 15% for tumors 3 to 5 cm, and 30% for tumors more than 5 cm (P = 0.0018). The 10‐year actuarial pelvic failure rate in Stage IIA was 10% for tumors less than 3 cm, 28% for tumors 3 to 5 cm, and 20% for tumors more than 5 cm (P = 0.09). Stage IIB unilateral nonbulky tumors (less than 5 cm) had a 20% pelvic failure rate compared with 28% for bilateral lesions and 35% for unilateral bulky tumors (more than 5 cm) (P = 0.35). In Stage IIB, pelvic failures were greater when disease extended into the lateral parametrium (30%) compared with medial parametrial involvement only (17%) (P = 0.01). In Stage III unilateral nonbulky tumors, the pelvic failure rate was 28% compared with 45% to 50% for unilateral bulky lesions (P = 0.002). Bilateral parametrial disease in Stage IIB did not increase the pelvic failure rate (21% in both subgroups) (P = 0.83), whereas in Stage III, bilateral parametrial involvement was associated with a 48% pelvic failure rate versus 28% for unilateral extension (P ≤ 0.01). Five‐year disease‐free survival (DFS) rates for IB tumors less than or equal to 3 cm was 90% versus 67% for tumors more than 3 cm (P = 0.01). In Stage IIA tumors less than or equal to 3 cm, 5‐year DFS was 70% versus 45% for tumors more than 3 cm. Patients with Stage IIB nonbulky tumors (less than or equal to 5 cm in diameter) had better 10‐year DFS (65% to 70%) compared with those with bilateral bulky tumors (45% to 55%) (P = 0.10). Stage I11 patients with unilateral nonbulky tumors had a 55% 10‐year DFS compared with 35% to 40% for bulky tumors or bilateral parametrial involvement (P = 0.002). The authors concluded that clinical stage and size of tumor are critical factors in the prognosis, therapy selection, and evaluation of results in carcinoma of the uterine cervix.
Thirty patients with adenocarcinoma of the fallopian tube, treated between 1950 and 1981, were studied. Median age was 55 years, and mean parity was 1.3. Bleeding or discharge occurred as a presenting complaint in 47% of patients, abdominal distention or mass in SO%, and pain in 30%. Lesions were staged using a system analogous to the International Federation of Gynecology and Obstetrics (FIGO) classification fdr ovarian carcinoma. Nine patients had Stage I disease; 11, Stage II; 7, Stage III; and 3, Stage IV. Histologic differentiation was Grade 1 in 39% of the patients, Grade 2 in 18%, and Grade 3 in 43%. Primary surgical treatment consisted of total abdominal hysterectomy and bilateral salpingectomy in 70% of the patients; 23% had more extensive surgery, whereas 13% had less extensive surgery. Three patients with Stage I tumors were treated with surgery alone, and the remainder received postoperative radiation, chemotherapy, or both. Survival was unrelated to grade, but highly dependent upon stage. Survival at 5 years was 56% for Stage I, 27% for Stage 11,14% for Stage 111, and 0% for Stage IV. Four of five patients treated after surgery with a combination of cisplatin, doxorubicin, and cyclophosphamide (PAC) survived at least 3 years. Patterns of initial treatment failure showed 56% with a component of pelvic failure, 50% with a component of upper abdominal failure, and 44% with extraperitoneal metastases as a component of failure. These results suggest the need for aggressive postoperative adjuvant therapy targeted at upper abdominal and distant sites for metastasis in all lesions beyond Stage I.
The growth of human cancer cells from lung, breast, and uterine tumors was selectively inhibited in a dose-dependent manner by ozone at 0.3 to 0.8 part per million of ozone in ambient air during 8 days of culture. Human lung diploid fibroblasts served as noncancerous control cells. The presence of ozone at 0.3 to 0.5 part per million inhibited cancer cell growth 40 and 60 percent, respectively. The noncancerous lung cells were unaffected at these levels. Exposure to ozone at 0.8 part per million inhibited cancer cell growth more than 90 percent and control cell growth less than 50 percent. Evidently, the mechanisms for defense against ozone damage are impaired in human cancer cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
