Endometrium and ovarian cancer synchronous to endometriosis--a retrospective study of our experience of 7 years

PURPOSE

Although endometriosis is a benign disorder, recent studies suggest that endometriosis could be viewed as a neoplastic process. The objective of this study is to explore the epidemiology of synchronous neoplasms (SPN) in women with severe endometriosis.

PATIENTS & METHODS

The prevalence of SPN in cases with endometriotic ovarian cysts that underwent surgery at "Lito" Maternity Hospital of Athens and at Anticancer Institute of Bucharest was investigated. The review period was from the year 2000 to 2008. The medical records and pathology were reviewed to confirm the diagnosis and stage of tumors.

RESULTS

Five women with synchronous cancer of the genital tract were identified. All of our patients had a grade-I endometrioid carcinoma of the uterus (Ia in 3, Ib in 2). Myometrium was invaded in less than 1/3, in 4 cases, and less than 1/2 in one case. Similarly, 4 out of 5 ovarian cancers were endometrioid, while one was serum cystadenosarcoma. All of the ovarian malignancies were grade I (Ib in 3 and Ia in 2). The median diameter of the ovarian neoplasias was of 4.3 cm, as opposed to 4.5 cm that was the median diameter of all endometrioid cysts. When the larger ovarian malignant cyst in each patient was accounted, the median diameter was calculated as having 5.8 cm.

CONCLUSIONS

Women with synchronous primary cancers of the endometrium and ovary have distinct clinical characteristics including younger age, premenopausal status, and nulliparity. This suggests that a hormonal "field effect" may account for the development of these simultaneous endometrioid cancers, supporting the theory of estrogen receptors.

[Incidence of synchronous primary neoplasms of the female reproductive tract in women with ovarian endometriosis: a retrospective analysis of 811 cases]

PURPOSE

Although endometriosis is a benign disorder recent studies suggest endometriosis could be viewed as a neoplastic process. Objective of this study is to explore the epidemiology of synchronous neoplasms (SPN) in women with severe endometriosis.

PATIENTS & METHODS

The prevalence of SPN in cases with endometriotic ovarian cysts that underwent surgery at "Lito" Maternity hospital of Athens and at Anticancer Institute of Sophia was investigated. The review period was 2000 through 2009. The medical records and pathology were reviewed to confirm the diagnosis and stage of tumors.

RESULTS

5 women with synchronous cancers of the genital tract were identified. All of our patients had a grade-I endometrioid carcinoma of the uterus (Ia in 3, Ib in 2). Myometrium was invaded less than 1/3 in 4 cases and less than 1/2 in one. Similarly, 4 out of 5 ovarian cancers were endometrioid, while one was serum cystadenosarcoma. All of the ovarian malignancies were grade I (Ib in 3 and Ia in 2). Median diameter of the ovarian neoplasias was 4.3 cm, in contradiction to 4.5 cm that was the median diameter of all endometrioid cysts. When only the larger ovarian malignant cyst in each patient was accounted, then median diameter was calculated as 5.8 cm.

CONCLUSIONS

Women with synchronous primary cancers of the endometrium and ovary have distinct clinical characteristics including younger age, premenopausal status, and nulliparity. This suggests that a hormonal "field effect" may account for the development of these simultaneous endometrioid cancers, supporting the theory of estrogen receptors.

Prevalence of severe pelvic inflammatory disease and endometriotic ovarian cysts: a 7-year retrospective study

INTRODUCTION

The purpose of this study was to delineate the association between endometriosis and pelvic inflammatory disease (PID) and the prevalence of this coexistence.

MATERIALS & METHODS

The records of all patients with endometriotic ovarian cysts treated at the 3rd Department of Obstetrics and Gynecology of the University of Athens and in "Lito" Maternity Hospital of Athens from 2000 through 2007 were reviewed.

RESULTS

During this 7-year period 720 women underwent surgery due to endometriotic ovarian cysts. The average age was 40.9 years (range: 17-70). Median diameter of the cysts was 4.495 cm and 59% were located in the right ovary. PID was identified in 21 (2.9%) cases. The average age of these women was 31 years (range: 21-39). Half of the women presented with fever (10/21; 47.6%). Ultrasound examination was performed in all women, followed by laparoscopy. In 47.6% (10/21) the PID abscess was located in the right ovary and the rest (52.38%) in the left. The mean diameter of the endometriotic cysts in these women was 3.52 cm. Laparoscopy was the treatment of choice in all the women with the exception of five cases, where due to technical difficulties during laparoscopy, a laparotomy was performed. In all the cases with PID, abscesses were evacuated laparoscopically. No operative complications were observed.

CONCLUSIONS

Endometriosis and PID are two conditions that can easily confuse the physician in setting the diagnosis, especially in the situation where they co-exist. In our study we report that the prevalence of PID in women with endometriosis is sufficiently higher than the prevalence in the general population.

Prevalence of acute hemoperitoneum in patients with endometriotic ovarian cysts: a 7-year retrospective study

INTRODUCTION

Endometriosis is a quite common condition in women of reproductive age. The purpose of this study is to delineate the association between hemoperitoneum and endometriosis.

MATERIALS & METHODS

The records of all patients with endometriotic ovarian cysts treated at the 3rd Department of Obstetrics and Gynecology of the University of Athens and at "Lito" Maternity Hospital of Athens from 2000 through 2007 were reviewed.

RESULTS

During this 7-year period 720 women underwent surgery due to endometriotic ovarian cysts. The average age was 40.9 years (range: 17-70). The median diameter of the cysts was 4.49 cm and 59% were located in the right ovary. Hemoperitoneum was identified in 16 (2.22%) of them. The average age of these women was 28.5 years (range: 22-44). Ten (62.5%) of these women presented with acute and strong abdominal pain and moderate signs of cardiovascular shock. The rest presented with abdominal pain and distension worsening at the onset of menses, nausea and/or vomiting and hemorrhagic fluid in the pelvis. Ultrasound examination was performed in all women and afterwards they underwent laparoscopy to identify the source of bleeding. In all cases a ruptured endometriotic cyst was found. In 68.8% (11/16) the ruptured cyst was located in the left ovary and the rest (31.2%) in the right. A thorough examination did not reveal any other sources of bleeding. No operative complications were observed.

DISCUSSION

The simultaneous occurrence of ascites and endometriosis is rare. A physician, though, must always take into consideration endometriosis in the differential diagnosis of ascites and acute abdominal pain or pelvic mass.

Immunomodulatory effect of three-day continuous administration of clarithromycin for experimental sepsis due to multidrug-resistant Pseudomonas aeruginosa

Based on former animal studies showing the effect of clarithromycin in experimental sepsis by multidrug-resistant Pseudomonas aeruginosa following administration of single doses, the significance of its administration for three consecutive days was evaluated. Acute pyelonephritis was induced in 20 rabbits after inoculation of the test isolate in the renal pelvis. Therapy was administered upon signs of sepsis in group B; A served as control. Survival was recorded; monocytes were isolated for determination of ex vivo TNFalpha secretion. Quantitative cultures of organs were performed after death. Mean survival of groups A and B was 2.65 and 7.95 days respectively. At 24 hours, serum malondialdehyde of group B, which is an index of the oxidant status in serum, was lower than A. Ex vivo release of TNFalpha by the isolated monocytes of group B was lower than A at 3.5 and 48 hours. Tissue bacterial load was similar in two groups after animal death. It is concluded that clarithromycin possessed considerable immunomodulatory effects restraining release of TNFalpha from blood monocytes.

Analysis of beta-catenin mutations and alpha-, beta-, and gamma-catenin expression in normal and neoplastic human pituitary tissues

The cadherin-catenin system mediates Ca(2+)-dependent cell-cell adhesion, and genetic alterations in these molecules play a significant role in multistage carcinogenesis. Mutations in the beta-catenin gene, mostly affecting exon 3, have been detected in malignant cell lines and in primary tumors. Immunohistochemical abnormalities in alpha-, beta-, and gamma-catenin have been reported in malignant and benign tumors, and nuclear localization of beta-catenin has been associated with mutations in exon 3 of this gene. Mutational analysis of exon 3 of the beta-catenin gene was undertaken by polymerase chain reaction (PCR) and sequencing using genomic DNA extracted from frozen tissues, including 4 normal pituitaries, 22 pituitary adenomas, and one pituitary carcinoma. Frozen sections from these cases were used for immunohistochemical detection of beta-catenin. We also analyzed immunohistochemical expression of alpha-, beta-, and gamma-catenin by paraffin sections from 154 pituitary tumors, including 148 adenomas and 6 carcinomas. Genomic DNA was extracted from paraffin sections of 2 gonadotroph tumors showing nuclear staining for beta-catenin and was used for PCR and sequencing of exon 3 of the beta-catenin gene. No mutations in exon 3 of the beta-catenin gene were found in any of the 23 cases analyzed by PCR and sequencing. In addition, the 2 cases studied by paraffin section immunohistochemistry, with nuclear staining for beta-catenin, were negative for mutations in this exon. Normal pituitary expressed all three catenin proteins. Immunostaining usually showed a membranous pattern of reactivity and was generally stronger in normal pituitary than in the adjacent adenomas. Stains for alpha-catenin were positive in fewer tumors than for beta-catenin. The lowest frequency immunopositive tumors and the weakest immunostaining was for gamma-catenin. All medically treated prolactinomas were negative for gamma-catenin, whereas treated growth hormone adenomas were less often positive for both alpha- and gamma-catenin than for untreated tumors. The percentage of positive cases for beta-catenin was the same in these two groups. Most pituitary carcinomas were negative for both alpha- and gamma-catenin but were beta-catenin positive. These results indicate that (i) mutations in exon 3 of the beta-catenin gene are uncommon in pituitary tumors, and (ii) expression of alpha-, beta-, and gamma-catenin is decreased in pituitary adenomas compared to normal pituitary tissues.
