“…During the first and second trimesters, especially by the 24th week, surgical treatment for gastric cancer should be immediately performed without regard for the pregnancy. McLean and associates [1] stated that rectal cancer detected in the first trimester should be resected without intentionally interrupting the pregnancy. They noted that all 8 reported cases undergoing operation during the first trimester survived and 3 living children were born.…”

“…Gastric cancer associated with pregnancy is rare and the information on this particular subject is limited, whereas cancer of the large bowel during pregnancy has occasionally been reviewed [1,2]. Although there were individual clinical case reports of gastric cancer during pregnancy [3][4][5][6][7][8], no analysis of the clinical features and prognosis has been documentated.…”

Prognosis in gastric cancer associated with pregnancy

Gastric cancer concomitant with pregnancy is rare. In order to determine the clinical problems and practical guidelines on this particular subject, 61 Japanese patients were analyzed for clinical features and the results of obstetric and surgical treatment corresponding to the time of detection of the gastric cancer during the gestational period. The data indicated a limitation in diagnostic approaches caused by pregnancy and difficulty in saving both the mother and the fetus. Only 20 (58.8%) of the pregnant women underwent both obstetric treatment for the fetus and surgical treatment for gastric cancer. Fifty-nine of the gastric cancer cases (96.7%) were advanced and resectability was consistently low (47.5%). The patients who received gastrectomy had a high incidence of hospital death (22.7%) and a poor prognosis--21.1% 3-year survival. Based on the authors' cases of both early and advanced gastric cancer associated with pregnancy, the importance of early detection by gastroendoscopy is emphasized.

The Incidence of Colorectal Cancer During Pregnancy in Japan: Report of Two Cases and Review of Japanese Cases

et al. 1998

Colorectal cancer during pregnancy is very rare. We report two additional cases of rectal carcinoma. A 34-year-old woman with an obstructive adenocarcinoma of the rectal region was diagnosed at labor. A 35-year-old woman with an adenocarcinoma of the rectal region was diagnosed at 32 weeks of gestation and underwent a cesarean section and rectal resection at 35 weeks of gestation. A retrospective review of the Japanese literature was performed to identify patients who appeared to have primary colorectal cancer during pregnancy. Thirty-six patients with colon cancer (75.0%), 10 (20.8%) with rectal cancer, and two (4.2%) of unknown sites have been reported in Japanese series. The average age of the mother was 32.2 years. The calculated incidence of colorectal cancer among Japanese pregnant women was one case per 502,316 live births during the years between 1986 through 1995. Although the majority of colorectal cancers diagnosed during pregnancy are rectal carcinomas, the patients in Japan were predominantly complicated by colon cancer. The fetal risk seems small, because there were no cases of colorectal cancer metastatic to the products of conception.

“…In general, if the tumor is discovered before the 20th week of gestation, treatment of the cancer should have priority. After the 20th week of gestation, surgery is postponed until fetus viability is reached (usually at 28-32 weeks) [2,4]. Our patient underwent surgery at 32 weeks of gestation because the serious maternal general condition required immediate delivery and because the fetus was thought to be viable.…”

A 37-year-old pregnant Japanese woman presented with right upper quadrant pain and pitting edema of the lower extremity. She had become pregnant via intrauterine insemination after a long history of infertility. She was admitted for suspected toxemia. Abdominal ultrasonography revealed multiple liver tumors, confirmed by computed tomography. Colonoscopy showed a tumor of the transverse colon diagnosed as a signet-ring cell carcinoma following biopsy. Elective cesarean section was performed at 32 weeks of gestation, and a normal infant (1.690 kg) was delivered. However, the tumor of the transverse colon was considered unresectable, and she died 1 month later. Necropsy confirmed extensive spread of the colon cancer. The tissue contained no estrogen or progesterone receptors. Certain colorectal cancers presenting during pregnancy exhibit a biologically aggressive behavior resulting in a poor prognosis.
