Radical ilioinguinal lymphadenectomy

Radical ilioinguinal lymphadenectomy remains the mainstay of treatment for certain genitourinary carcinomas either with the propensity for or with clinical evidence of metastases to the inguinal-pelvic region. The most frequent indication for this procedure in urologic practice is carcinoma of the penis, followed by carcinoma of the urethra, scrotum, and testis with scrotal invasion. This article reviews the anatomy of the inguinal and iliac region and presents a detailed discussion of the surgical technique.     

Management of regional lymphatic drainage in carcinoma of the penis.

Radical ilioinguinal lymphadenectomy remains the mainstay of treatment for certain genitourinary carcinomas either with the propensity for or with clinical evidence of metastases to the inguinal-pelvic region. The most frequent indication for this procedure in urologic practice is carcinoma of the penis, followed by carcinoma of the urethra, scrotum, and testis with scrotal invasion. This article reviews the anatomy of the inguinal and iliac region and presents a detailed discussion of the surgical technique and its most recent modifications.     

Squamous cell carcinoma of scrotum

Squamous cell carcinoma of the scrotum is a rare malignancy in the United States. This series includes the eighth reported case of this lesion in a black American. Surgery still remains the only effective therapeutic modality. The use of sentinel and superficial inguinal node biopsies was important in determining whether or not radical ilioinguinal lymphadenectomy was needed in 2 patients.     

Squamous cell carcinoma of the scrotum in a radiation technologist and the use of sentinel lymph node biopsy in recurrent disease

Squamous cell carcinoma (SCC) of the scrotum is an uncommon neoplasm. It has been described in many different occupations and is associated with a myriad of carcinogens, yet the etiology still remains a mystery. This is the first report of its occurrence in a radiation technologist. Additionally, the use of sentinel lymph node biopsy in SCC has been advocated as a safe method of limiting the morbidity associated with bilateral ilioinguinal dissections. This is the first report of its use in recurrent metastatic SCC of the scrotum.     

Management of carcinoma of the thyroid.

Greater precision has developed in recent decades in the selection of patients for operation for thyroid nodules suspicious for malignancy and in adapting operative procedures to the extent and pathologic variety of the individual thyroid carcinoma, when present. A thyroid lobectomy is considered to be the minimal operative procedure usually indicated for a suspicious thyroid nodule or carcinoma involving one lobe of the thyroid gland. Factors determining the extent of operation for thyroid carcinoma include the pathologic variety, gross distribution of the malignancy, and health status of the individual patient. Total or near total thyroidectomy should be considered for all patients with thyroid carcinoma except for single occult carcinomas and unilateral low grade angio-invasive carcinomas. Removal of lymph nodes in regions adjacent to the thyroid carcinoma is advisable, lateral neck dissections being reserved for patients with palpable lymphadenopathy, demonstrated metastases to lateral cervical lymph nodes, or a poorly differentiated carcinoma likely to metastasize to these lymph nodes. A modified radical lymph node dissection is satisfactory except for those carcinomas invading muscles in the neck. Anatomic neck dissections provide a better prognosis than incomplete lymph node procedures for patients with regional lymph node metastases. Following operation, patients should receive thyroid hormone therapy, be evaluated for possible treatment with radioactive iodine or other therapeutic measures, and be followed for evidence of recurrent disease as well as thyroid and parathyroid function. Adequate early operation is preferred to late ultraradical procedures, from standpoints of morbidity and prognosis. Unfavorable prognostic factors include extensive gross disease, poorly differentiated carcinoma present as the entire lesion or as foci in a differentiated carcinoma, and age over 40. With adequate surgical treatment, the prognosis for operable thyroid carcinoma is good.     

Thyreoidektomie und Lymphadenektomie

In benign goiter, thyroidectomy is only indicated in patients with nodular alterations of the complete thyroid gland. There is no evidence indicating that total thyroidectomy could improve the postoperative results in patients with Graves' disease. In Germany, thyroidectomy with cervicocentral lymph node dissection is the standard procedure for all differentiated thyroid carcinomas. However, there are no data to prove that this approach is superior to less radical procedures. Avoidance of reoperations and optimal conditions for effective postoperative radioiodine therapy are arguments for this aggressive strategy. In patients with medullary carcinoma or with detected ret-proto-oncogene mutations, thyroidectomy with cervicocentral lymphadenectomy should be the initial operation. The cervicolateral and mediastinal compartments should be dissected when clinically obvious lymph node metastases are present in patients with differentiated carcinomas. In patients with medullary carcinomas, persistently increased calcitonin levels after the initial operation are sufficient indication for this procedure. Thyroidectomy is an important part of the multimodal approach in patients with anaplastic carcinomas. The operative technique of thyroidectomy is presented as well as the technique of cervical lymphadenectomy in consideration of the lymphatic drainage of the thyroid gland.     

The role of ilioinguinal lymphadenectomy and significance of histological differentiation in treatment of carcinoma of the penis

We reviewed retrospectively the medical records of 58 patients treated for squamous cell carcinoma of the penis who were followed for more than 3 years or until they died. Tissue sections from all patients were reviewed. Of 15 patients with stage I disease 11 underwent partial penectomy, and 4 underwent partial penectomy and immediate ilioinguinal lymphadenectomy; none died of cancer. Nine patients with stage II and 9 with stage III disease underwent partial or total penectomy and immediate ilioinguinal lymphadenectomy, and 5-year survival was 100 and 75%, respectively. Of 20 patients with clinical stage II disease who did not undergo immediate ilioinguinal lymphadenectomy 18 had metastasis to the groin. Of these 18 patients 12 underwent delayed ilioinguinal lymphadenectomy but only 1 survived more than 5 years. We evaluated the possible significance of the degree of histological differentiation of the primary tumor to the course of the disease. Of the 23 cases of carcinoma in situ or well differentiated disease only 1 became metastatic, while of the 35 cases of moderately to poorly differentiated disease 31 metastasized to the groin. Vascular invasion of cancer cells in the primary tumor was another indicator for poor prognosis.     

Pro and contra lymphadenectomy in papillary and follicular thyroid gland carcinoma

Patients with papillary and follicular thyroid carcinomas are said to have an excellent long-term prognosis. However, over 90% of papillary carcinomas have synchrone lymph node metastases. Based on clinical, histopathologic and molecular-biological factors, different patient groups can be defined with an increased recurrence rate and disease related mortality-rate of up to 50% in the long-term follow-up of 30 years. Therefore, not only the extent of the surgical resection of the thyroid cancer but also the lymph node dissection as an oncologic correct surgical procedure is of great importance. Although the position of surgical lymphadenectomy is still discussed controversially there are increasing reasons to support the concept of a radical initial operation following the rules of oncologic surgery. We consider total thyroidectomy and modified neck-dissection as the standard operation in well differentiated thyroid carcinoma. In unilateral carcinoma both the central and the ipsilateral cervico-lateral lymph node compartments are dissected. In multicentric bilateral carcinomas a bilateral cervico-central and cervico-lateral lymphadenectomy has to be performed.     

Gemischtes Plattenepithel- und Adenokarzinom der weiblichen Urethra

We report a case of mixed squamous-cell carcinoma with adenocarcinoma of the female urethra. A 37 year old women who presented with a 3-month' history of obstructive voiding symptoms. Clinical investigation showed a urethra tumor of 2.5 x 3.5 cm. Needle biopsy revealed a grade 3 carcinoma. Staging resulted in local cancer disease, a 2.5 x 3.5 cm tumor surrounding the whole urethra with protruding the trigonum. We performed urethrectomy with resection of the bladderneck and cystoneostomy. During bladderneck resection we performed regional staging lymphadenectomy of the obturator lymph nodes. Histological investigation revealed a mixed squamous-cell carcinoma with adenocarcinoma and undifferentiated carcinoma of the urethra. Periurethral tissue showed lymphangiosis carcinomatosa with negative lymph nodes. To exclude involvement of regional superficial lymph nodes we subsequently performed modified inguinal lymphadenectomy without evidence of advanced cancer disease.     

A case of advanced penile cancer treated with multimodal therapy--combination with tensor fascia lata myocutaneous flap

A 40-year-old male with advanced penile cancer, whose left inguinal node was ulcerated at the time of initial presentation, underwent multimodal therapy. Four cycles of chemotherapy were given from September 20, 1984 to February 8, 1985. Partial penectomy and left ilioinguinal lymphadenectomy with removal of left groin ejaculation were performed on February 20, 1985, followed by right ilioinguinal lymphadenectomy on March 20, 1985. The skin defect of the left groin was covered with tensor fascia lata myocutaneous flap. The patient is alive with no evidence of disease 30 months after the surgery.     

Pattern of lymph node metastases in patients with squamous cell carcinoma of the thoracic esophagus who underwent three-field lymphadenectomy

BACKGROUND/AIMS: Lymph nodes in patients with squamous cell carcinoma of the thoracic esophagus might be involved with metastases at cervical, mediastinal, and abdominal sites. The range of lymph node dissection is still controversial. The pattern of lymph node metastasis and factors that are correlated with lymph node metastasis affect the surgical procedure of lymph node dissection. The purpose of the present study was to explore the pattern of lymph node metastasis and factors that are correlated with lymph node metastasis in patients with esophageal cancer who underwent three-field lymphadenectomy. METHODS: Lymph node metastases in 230 patients who underwent radical esophagectomy with three-field lymphadenectomy were analyzed. The metastatic sites of lymph nodes were correlated with tumor location by chi-square test. Logistic regression was used to analyze clinicopathological factors related to lymph node metastasis. RESULTS: Lymph node metastases were found in 133 of the 230 patients (57.8%). The average number of resected lymph nodes was 25.3 +/- 11.4 (range 11-71). The proportions of lymph node metastases were 41.6, 19.44, and 8.3% in neck, thoracic mediastinum, and abdominal cavity, respectively, for patients with upper thoracic esophageal carcinomas, 33.3, 34.7, and 14%, respectively, in those with middle thoracic esophageal carcinomas, and 36.4, 34.1, and 43.2%, respectively, for patients with lower thoracic esophageal carcinomas. We did not observe any significant difference in lymph node metastatic rates among upper, middle, and lower thoracic carcinomas for cervical or thoracic nodes. The difference in lymph node metastatic rates for nodes in the abdominal cavity was significant among upper, middle, and lower thoracic carcinomas. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity than tumors at other thoracic sites. A logistic regression model showed that depth of tumor invasion and lymphatic vessel invasion were factors influencing lymph node metastases. CONCLUSIONS: Based on our data, cervical and mediastinal node dissection should be performed independent of the tumor location. Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancers than for cancers at other locations. Patients with deeper tumor invasion or lymphatic vessel invasion were more likely to develop lymph node metastases.     

Combined surgery and chemotherapy for retroperitoneal metastases of testicular carcinomas other than pure seminoma.

The results of treatment in 210 patients with testicular carcinomas other than pure seminoma are analysed. Patients with negative retroperitoneal nodes had a very good prognosis following lymph node dissection alone. Patients with positive nodes did much better after adjunctive chemotherapy than after post-operative irradiation. Patients with advanced disease showed significant improvement with intensive chemotherapy combined with surgery. Presently retroperitoneal lymphadenectomy combined with intensive chemotherapy seems to be the treatment of choice for metastatic testicular carcinomas.     

Clinical applications of sentinel lymph-node biopsy for the staging and treatment of solid neoplasms

A review of the clinical applications of sentinel lymph node (sN) biopsy has been performed with the aim of defining the rationale, the methods of detection, the accuracy, and the current indications to sN biopsy in different solid neoplasms. In melanoma patients, sN biopsy represents a standard procedure for staging purpose, although its therapeutic value is still under examination. The sN is an accurate method for the pathologic staging of the axilla in patients with early stage breast cancer, and it can be useful for the selection of patients with axillary metastasis who should undergo standard axillary dissection. In gynecologic malignancies, appreciable results are available in patients with vulvar and cervical cancer only. Patients with squamous cell vulvar cancer may benefit by sN biopsy because a complete bilateral inguino-femoral lymph-node dissection may be avoided whenever the sN is free of metastasis. As regards to cervical cancer, further studies are required with the combined technique (blue dye injection and gamma-probe guided surgery), which seems more promising, before abandoning pelvic lymphadenectomy in patients with histologically-negative sN. The experience in urologic cancer deals mainly with penile and prostate cancer; the modern procedures for the dynamic detection of sN are going to clarify its role in the surgical management of penile cancer; as regards to prostate cancer, very preliminary results suggest that the sN biopsy may enhance the pathologic staging of this neoplasm compared to modified pelvic lymphadenectomy, due to the individual variability of the lymphatic drainage of this cancer. In patients with clinically node-negative squamous head and neck cancer, the reliability of sN-guided neck lymph node dissection seems promising. The sN biopsy is also technically feasible in patients with differentiated thyroid cancer; however, the future role of this procedure in the clinical decision-making of these patients remains to be defined due to the questionable biological meaning of nodal metastases. Patients with non-small-cell lung cancer should be investigated by means of radiotracers injected at the time of thoracotomy or under CT-scan guidance in order to achieve a satisfactory identification rate (over 80%); the focused histopathologic staging of the sN improves current pathologic staging by conventional bi-valve assessment of all the lymph nodes of the surgical specimen; moreover, the prognostic role of isolated N2 metastasis can be better elucidated. In patients with gastrointestinal malignancies, the intraoperative lymphatic mapping with sN biopsy have suggested that the lymphatic drainage of the gastrointestinal tract is much more complicated than other sites, skip metastasis being rather frequent. In patients with gastric cancer, current data show that it can be detected by means of peritumoral injection of indocyanine green; the detection of tumor positive lymph nodes beyond the perigastric area could select patients amenable to D2 lymphadenectomy. As regards to colorectal cancer patients, the focused analysis of the sN may reveal disease that might otherwise go undetected by conventional surgical and pathological methods, and those patients which are upstaged can benefit by adjuvant chemotherapy. Finally, in patients with Merkel cell carcinoma, notwithstanding the limited experiences with sN biopsy, sN histology seems to predict regional lymph node status and may aid in selecting which patients are amenable to therapeutic lymph node dissection.     

Breast Cancer in Identical Twins with Different Clinical Course

Abstract: Recent discussions have questioned the need or benefit of radical axillary lymphadenectomy for some patients as part of treatment for breast carcinoma. An evaluation of the need for discontinuous lymphadenectomy is presented with proposal to eliminate lymphadenectomy in the breast-conserving therapy of some patients.
From 1977 through 1993, 101 breasts in 95 patients with breast carcinoma were treated by breast conservation without radical axillary lymphadenectomy.
At median follow-up of 76 months, only four patients (4.0% of cancers) had occurrence of axillary disease requiring invasive evaluation of delayed clinically positive axillae. One of the four patients had negative nodes. Two patients had positive lymph nodes without recurrent disease in the ipsilateral breast or distant metastasis. The fourth patient had distant metastasis, and a positive fine-needle aspiration biopsy of an axillary lymph node was sufficient for diagnosis. Discontinuous radical axillary lymphadenectomy was neither technically different nor more difficult that primary lymphadenectomy.
Some breast cancer patients may forego surgical evaluation of the axilla as part of their breast conservation therapy without compromise in adjuvant therapy decisions or detriment in outcome. The authors strongly recommend large prospective, clinical studies be performed in the near future.     

Pelvic and para-aortic lymphadenectomy in epithelial ovarian cancer. Report of a series of 86 cases

AIM OF THE STUDY: The impact of lymphadenectomy in therapeutic strategy of ovarian carcinomas is strongly debated. The aim of this retrospective study was to report a series of 86 patients with ovarian carcinoma who underwent pelvic and paraaortic lymphadenectomy. PATIENTS AND METHOD: From 1993 to 1998, a retroperitoneal lymphadenectomy was performed in 86 patients (median age: 54 years) during the first laparotomy (n = 52) or later (n = 34) for ovarian carcinoma stade I and II (n = 33), stade III and IV (n = 53). Sixty patients underwent pelvic and paraaortic lymphadenectomy with separate study of the different groups of nodes. RESULTS: There was a lymph node involvement in 48.8% of all cases and in 36% of stade I and II carcinomas. Lymph node involvement was observed for all histological types. It was present in both pelvic and paraaortic nodes in 52.3% of the patients N+. Its incidence was 46.1% in patients before chemotherapy and 52.9% in patients after chemotherapy. It may concern all anatomical location with a 5 to 31% frequency. There was no postoperative death and a low morbidity rate (13.9%). CONCLUSIONS: Retroperitoneal lymphadenectomy is feasible; it is a contribution to the tumoral cytoreduction and to a better classification of ovarian carcinomas. According to this series and to the other reported series, an initial, complete, pelvic and paraaortic lymphadenectomy should be recommended for all cases of ovarian carcinomas but prospective randomised trials are necessary to appreciate the impact of this lymphadenectomy on survival.     

Intraoperative lymphatic mapping and sentinel lymph node biopsy for Merkel cell carcinoma

BACKGROUND: Merkel cell carcinoma is a rare cutaneous neoplasm which commonly spreads to the regional lymph nodes. The feasibility of identifying the sentinel node in patients with clinically node-negative Merkel cell carcinoma was evaluated. METHODS: Sentinel lymphatic mapping was performed in 18 patients with stage 1 Merkel cell carcinoma using the combination of isosulphan blue dye and 99mTc-radiolabelled sulphur colloid. Patients with tumour metastasis in the sentinel node underwent complete dissection of the remainder of the lymph node basin. RESULTS: Eighteen patients underwent removal of 35 sentinel nodes. Two patients demonstrated metastatic disease in the sentinel lymph nodes; complete dissection of the involved nodal basin revealed no additional positive nodes suggesting that the sentinel lymph node had been identified. The node-negative patients received no further surgical therapy, with no evidence of recurrent disease in the sentinel nodal basin at a median of 7 months' follow-up. CONCLUSION: Sentinel node biopsy is feasible in patients with Merkel cell carcinoma. It can be used to stage patients and provides important prognostic information. In those with subclinical nodal disease, it may direct early regional lymphadenectomy but the effect of such surgery on survival remains unclear.

Changing clinical, pathologic, therapeutic, and survival patterns in differentiated thyroid carcinoma.

Records of 792 patients with differentiated thyroid carcinoma seen at the Lahey Clinic Foundation over a 40-year period were analyzed; 631 patients had a minimum followup period of 15 years. Differentiated types currently constitute nearly 90% of thyroid carcinomas. The clinical presentation has improved substantially through the years, and the results of treatment generally have improved. The per cent of patients with primarily incurable and locally unresectable disease or distant metastases has decreased from 7% before 1950 to 1% currently, and this group resulted in almost one third of the total fatalities and one half of fatalities within the first 5 years after treatment. Clear relationships were demonstrated between older age, men, extraglandular extension, blood vessel invasion, major capsular involvement, multifocal disease, and higher mortality rates. Lymph node metastases were found to exert a protective effect in all categories of disease analyzed, and this effect was directly related to the number of lymph node metastases present such that no deaths occurred in those patients who had more than 10 node metastases. Surgical treatment recommended is subtotal thyroidectomy for patients at high risk of death from disease as defined by combinations of age, sex, and extraglandular extension. Patients at low risk or with small carcinomas can be treated satisfactorily by lobectomy. Lymph node resections should be of a limited type or a modified neck dissection and should be performed only therapeutically. No improvement, as judged by mortality or recurrence rates, could be demonstrated by the use of radio therapy after surgery, and its use should be discouraged. Thyroid hormone administered for suppression of endogenous thyroid-stimulating hormone production improved mortality rates significantly in patients with papillary and mixed forms of carcinoma in all age groups but did not affect survival in patients with follicular carcinoma of the thyroid.20
