Postmastectomy lymphangiosarcoma: a reappraisal of the concept--a critical review and report of an illustrative case

Is Immediate Lymphatic Reconstruction on Breast Cancer Patients Oncologically Safe? A Preliminary Study

Background

In breast cancer patients receiving axillary lymph node dissection (ALND), immediate lymphatic reconstruction (ILR) with lymphovenous anastomosis is an emerging technique for reducing the risk of arm lymphedema. However, the oncologic safety of surgically diverting lymphatic ducts directly into venules in a node-positive axilla is still a concern of inadvertently inducing metastasis of remaining cancer cells. This study aimed to assess the oncologic safety of ILR.

Methods

From January 2020 to January 2022, 95 breast cancer patients received ALND, and 45 of them also received ILR. Patients with recurrent cancer, with follow-up less than 12 months, and with missed data were excluded. Variables were compared between ILR and non-ILR groups, and the outcome of interest was the rate of distant recurrence after follow-up for at least 1 year.

Results

Thirty-four patients in the ILR group and 32 patients in the non-ILR group fulfilled the inclusion criteria for analysis. No statistically significant difference was noted between groups in terms of age, body mass index, type of breast surgery, pathologic cancer staging, histologic type and grade of breast cancer, molecular subtypes, frequency of axillary lymph node metastasis, or adjuvant therapy. For the patients receiving follow-up for at least 1 year, no statistically significant difference was found in terms of distant recurrence rates between ILR and non-ILR groups (P = 0.44).

Conclusion

For breast cancer patients receiving ALND, ILR with lymphovenous anastomosis is oncologically safe, within an average follow-up period of 21 months.

Postmastectomy Angiosarcoma: Ultrastructural Study of a Case

The ultrastructural findings of a case of Stewart-Treves syndrome are reported. The authors believe that some features, never described before, confirm the truly vascular nature of this neoplasm.

Rapidly progressive metastatic multicentric epithelioid angiosarcoma of the small bowel: a case report and a review of literature

BACKGROUND

Angiosarcoma is a rare high-grade neoplasm that frequently involves the skin and subcutaneous tissue. Rarely, angiosarcoma can occur in the gastrointestinal tract where it frequently exhibits multicentric epithelioid morphology.

DESIGN

We report a case of multicentric epithelioid angiosarcoma (EAS) of the small intestine in a 73-year-old male patient who presented with weakness and melena, and was found to have bleeding lesions in the small intestine on upper gastrointestinal endoscopy. In addition to this case, we extensively reviewed the clinical and pathological features of previously reported cases of angiosarcoma of the small intestine in the English literature since 1970.

RESULTS

Our patient presented with rare and aggressive EAS of the small intestine. Despite surgical resection of the lesions, the patient continued to worsen and developed rapidly progressive metastatic disease. He died within 4 months of the diagnosis.

CONCLUSIONS

Angiosarcoma, especially of the deep tissues and the gastrointestinal tract, is very aggressive and rapidly metastatic. The survival rate in these patients is extremely poor, and most patients die within 6 months to 1 year of the diagnosis. Treatment usually involves surgical resection of the bleeding lesions and frequent blood transfusions for symptom alleviation.

Radiation induced angiosarcoma a sequela of radiotherapy for breast cancer following conservative surgery

Radiation induced angiosarcomas (RIA) can affect breast cancer patients who had radiotherapy following conservative breast surgery. They are very rare tumors and often their diagnosis is delayed due to their benign appearance and difficulty in differentiation from radiation induced skin changes. Therefore it is very important that clinicians are aware of their existence. We report here a case of RIA followed by discussion and review of literature.

Angiosarcoma of the small intestine: a possible role for thalidomide?

An 85-yr-old male presented with complaints of a 40-lb weight loss and a dull left upper quadrant abdominal pain. He also complained of decreased appetite, generalized weakness, generally not feeling well, and a dull left upper quadrant abdominal pain that was not relieved by food. He had a ventral and a left-sided inguinal hernia. Laboratory investigations revealed iron deficiency anemia, the cause of which was not apparent despite extensive investigation including computerized tomographic scans, esophagogastroduodenoscopy, and small-bowel follow-through examination. Surgical exploration for possible angiodysplasia, malignancy, and/or mesenteric ischemia revealed an incarcerated hernia, and the histopathological examination of the surgical specimen revealed high-grade angiosarcoma. The tumor showed strong positivity for vimentin and CD31 and a focal positivity for Factor VIII and CD34. At that time he was found to have hepatic metastases. He was started on thalidomide as an experimental measure with no change in the performance status and increasing evidence of necrosis in the metastatic lesion.

Primary cutaneous B-cell lymphoma of the leg in a chronic lymphedematous extremity

This is a case report of a woman who had chronic lymphedema on one leg and who developed a primary cutaneous large B-cell lymphoma of the leg at that site. She received radiotherapy and did not show any systemic involvement thereafter. Other neoplasms may appear in a clinical setting of chronic lymphedema, namely, lymphangiosarcoma (Stewart-Treves), melanoma, and metastatic carcinoma. There are four other reports in the English literature of cutaneous lymphoma arising in an extremity with chronic lymphedema.

Postmastectomy malignant lymphoma

Postmastectomy lymphedema (PML) is a morbid condition occurring in patients with breast carcinoma treated with radical/modified radical mastectomy. Postmastectomy angiosarcoma (PMA) is the most common neoplasia seen in these patients. Primary malignant lymphoma arising in PML is a rare neoplasia and 3 cases have been reported until now. In this report a patient with diffuse large cell lymphoma (DLCL) arising in PML is reported and the other three cases are reviewed.

Radiation-Induced Sarcoma Following Treatment of Breast Cancer

BACKGROUND: Radiation therapy (XRT) is an important modality in the treatment of cancer, and XRT is now commonly utilized in the treatment of early-stage breast cancer. However, its use has occasionally resulted in the development of secondary malignancies. We present a critical review of radiation-induced sarcoma (RIS) that develops after irradiation for the treatment of breast cancer. METHODS: The case of a patient who developed sarcoma after radiation for breast cancer is presented, and current literature on RIS is reviewed. The role of XRT in the development of RIS is examined, and the evaluation and treatment of these malignancies are reviewed. Results: RIS occurs in 0.2% of patients following treatment of breast cancer. The role of radiation in the development of RIS has been clearly demonstrated. Clinical presentation varies, and diagnosis is commonly delayed. Treatment consists of wide surgical excision. The role of chemotherapy is controversial. CONCLUSIONS: The occurrence of RIS following treatment of breast cancer is rare. Its development has an average latency of over 10 years and likely correlates with the dose and technique of the radiation treatment. The prognosis of patients with RIS following treatment for breast cancer is poor predominantly due to a delay in diagnosis. However, the benefit derived by breast cancer patients from XRT far outweighs the risk of RIS and should not affect the decision to treat these patients with this modality.

Multicentric angiosarcoma of the gastrointestinal tract

A case of multicentric gastrointestinal angiosarcoma suffering from severe melena is presented. Endoscopical examination revealed two polyps in the stomach and duodenum. Histological examination showed angiosarcoma. Although a gastroduodenectomy was performed, severe melena continued, and the patient developed respiratory failure and died. At autopsy, multiple hemorrhagic tumors were present from the duodenum to the cecum. Histologically the tumors demonstrated vasoformative structure and were immunohistochemically positive for von Willebrand factor (factor VIII related antigen), CD34, and CD31. Numerous metastases were found in various organs, including the lungs, bones, liver, gall-bladder, and lymph nodes. The patient had received hemodialysis for 21 years due to chronic renal failure. Long-term dialysis had been associated with various malignancies. Multicentric development of angiosarcoma in the present case may also be related to long-term dialysis.

A case of malignant transformation in thoracic vertebral hemangioma following repetitive irradiation and extraction

We report a rare case of thoracic vertebral hemangioma which developed into angiosarcoma during the course of repetitive operations and irradiation. A 44 year old female was operated on for hemangioma of the first thoracic vertebra. The diagnosis of hemangioma was confirmed histopathologically with the specimen from the first operation. The tumor developed multiple lesions later in the clinical course after the first operation, these lesions were removed in four consecutive operations and each histological diagnosis was that of hemangioma. Throughout the period of these operations, the patient was treated with steroid, and with radiotherapy simultaneously. The patient underwent the fifth operation for the recurrence of the tumor on 26 March 1990, and the histopathological diagnosis was not hemangioma but hemangiosarcoma which was considered a malignant transformation. The tumor cells immunohistochemically revealed positive staining with UEA-I, Factor-VIII, as the tumor immunohistochemically showed a vascular endothelioid nature.

Cutaneous secondary follicular centre cell lymphoma in association with lymphoedema praecox

We report a patient who developed cutaneous metastases in a lymphoedematous leg, from a follicular centre cell lymphoma, in a setting of lymphoedema praecox and recurrent deep-vein thromboses. To our knowledge, this is the first report of such a case. We discuss the possible causes for this localization.

Stewart-Treves syndrome. A report of two cases with a review of Japanese literature

Two cases of postmastectomy lymphangiosarcoma seen at our department are reported. One case, treated by amputation, died 1 year 4 months later and the other case, treated by local excision followed by amputation, died 7 months later. Twenty cases from the Japanese literature, including our 2 cases, are reviewed herein. The initial treatment for the other 18 cases was as follows: amputation in 8 cases, local excision in 2, radiotherapy in 4 and chemotherapy in 4. Fifteen of 16 cases eligible for follow up were dead within 20 months after treatment. Although the knowledge available as to the results of the treatment of postmastectomy lymphangiosarcoma is still insufficient to indicate the optimal therapeutic approach, early recognition of the lesion and prompt radical ablative surgery seem to offer the best chance for survival.

Radiation-induced angiosarcoma

A 47-year-old woman presented with an angiosarcoma of the terminal ileum 14 years after receiving adjuvant radiation therapy for ovarian dysgerminoma. Her clinical course is described, and the previously reported cases of radiation-induced angiosarcoma are reviewed.

Stewart-Treves syndrome: an histogenetic (ultrastructural and immunohistological) study

One case of the so-called "Stewart-Treves syndrome" (STS), appearing on a lymphoedematous arm complicating radical mastectomy for breast cancer, was characterized electronmicroscopically and immunohistologically, in order to elucidate its disputed (epithelial vs endothelial) histogenesis. Epithelial and endothelial differentiation markers used comprised: antibodies against keratin, vimentin, factor VIII-related antigen (F VIII-RA), HLA-DR antigens and the lectin Ulex europeaus agglutinin I (UEA I). At the ultrastructural level, neoplastic cells were found to contain typical Weibel-Palade bodies, whereas by immunohistological techniques they proved to be keratin-negative/vimentin+, F VIII-RA+, UEAI+, HLA-DR+. These results rule out a possible epithelial differentiation and strongly favour an endothelial one for STS.

Non-Hodgkin's lymphoma of the skin associated with chronic limb lymphoedema

Cutaneous non-Hodgkin's lymphoma developed within a leg affected by chronic lymphoedema. The lymphoedema had followed radiotherapy to bony metastases from a carcinoma of the prostate. Eighteen months after the development of the cutaneous tumours, extracutaneous involvement by the lymphoma became apparent. This is the second report of a non-Hodgkin's lymphoma appearing within a lymphoedematous limb. The possible reasons for such an unusual localization are discussed. Our case report illustrates that cutaneous tumours other than lymphangiosarcomas may localize to a lymphoedematous limb and clinically simulate the Stewart-Treves syndrome.

Concomitant angiosarcoma and carcinoma of the breast: a case report

A case of concomitant angiosarcoma and carcinoma of the left breast in a forty-three year old woman is described. Following a diagnosis of angiosarcoma she was treated by simple mastectomy. Five months later, left axillary lymph node biopsy showed metastatic adenocarcinoma. Retrospective examination of the mastectomy specimen disclosed a concomitant but separate adenocarcinoma. The patient remains well after 3 years. The implications of this rare association are discussed and the long survival gives an opportunity to review the prognosis in breast angiosarcomas.

Histogenesis of post-mastectomy angiosarcoma--an ultrastructural study

An example of post-mastectomy angiosarcoma was studied by electron microscopy to determine its histogenesis. Unequivocal evidence of endothelial differentiation was found in well and poorly differentiated areas. Positive staining for factor VIII related antigen and negative staining for epithelial membrane antigen further confirmed that the tumour was a true angiosarcoma rather than a peculiar form of carcinomatous metastasis.

Angiosarcoma in irradiated post-mastectomy chest wall

A 61-year-old woman developed an angiosarcoma in the irradiated chest wall 2 1/2 and 4 years after mastectomy for a carcinoma of breast. The two sets of tumours were morphologically distinct and differed immunohistochemically. The short interval between post-operative irradiation and presentation of the angiosarcoma is unusual. The case is discussed in relation to others of allied type.

Electron microscopic observations of lymphangiosarcoma arising from chronic lymphedema

Lymphangiosarcoma, so-called Stewart-Treves syndrome, originating from the edematous left leg after hysterectomy in a 53-year-old woman has been studied by light and electron microscopy. Histologically the tumor was composed of either vascular channels or solid nests of the neoplastic cells having a large hyperchromatic nucleus with a single or multiple prominent nucleoli. The inner surface of the vascular channels was lined by either single or several layers of identical cells. Erythrocytes were occasionally observed in the lumina of the vascular channels. By electron microscopy the maturation of the neoplastic cells differed considerably from one area to another even in the same section. The immature cells were clustered in groups and consisted of scanty cytoplasm and a large nucleus with prominent nucleoli, whereas some of the mature cells lining the lumina had rod-shaped tubulated bodies (Weibel-Palade bodies). Desmosomes were frequently observed between the neoplastic cells. Basal lamina was generally not continuous or not present although some vascular structures were completely surrounded by a basal lamina. An autopsy was performed but revealed no metastatic lesions in any organs or lymph nodes.

Lymphangiosarcoma

Forty-four cases of lymphangiosarcoma treated at Memorial Sloan-Kettering Cancer Center were reviewed. With the exception of four patients with primary lymphangiosarcoma of the scalp, all patients had had chronic lymphedema of the involved limb for many years, usually following mastectomy for breast carcinoma, but occasionally due to other cases. Although chronic lymphedema could be implicated in the etiology of lymphangiosarcoma in all patients with neoplasms of an extremity, a significant number of patients did not have a history of radiation therapy at the site where their tumor developed. Histologically, although there were no differences in the lymphangiosarcomas between any of the groups of patients, the morphology of the tumors was influenced in the individual patient by the size and anatomic site of the sarcoma. Early amputation seemed to give the best chance of long-term survival, with responses to wide resection, chemotherapy, and radiation therapy generally only of short duration. Amputation after local recurrence was ineffective in preventing pulmonary metastases and death. At present, early amputation appears to be the treatment of choice for patients with lymphangiosarcoma.
