Long-term survival after surgical resection of metachronous lung,brain and thyroid gland metastases from rectal cancer: A case report

Introduction and importanceBrain and thyroid metastasis from rectal cancer are uncommon, and the prognosis is poor. We report a patient with rectal cancer who developed metachronous lung, brain and thyroid metastases. Each metastatic lesion was curatively resected resulting in prolonged survival.Case presentationA 60-year-old male underwent rectal cancer resection, and the pathological diagnosis was tubular adenocarcinoma, pT2,pN1a,M0, pStageⅢa. Ten years after rectal resection, a solitary tumor in the left lung was detected. The tumor was resected thoracoscopically and the pathological diagnosis was metastatic tumor. Three years after the pulmonary resection, a solitary brain tumor was detected. The tumor was removed surgically, and the pathology was metastatic tumor. Two years after brain resection, a thyroid mass was detected. A partial thyroidectomy was performed and the pathology with immunohistochemical staining confirmed the thyroid lesion as a metastasis from the previous rectal cancer. Four years after thyroid resection (19 years after the initial rectal resection), he died from multiple lung and bone metastases.Clinical discussionColorectal metastases to the brain and thyroid gland are uncommon and are usually found with other distant metastases. Overall survival has been reported to be extremely poor. In this patient, lung, brain, and thyroid metastases were solitary and metachronous, and each lesion was curatively resected. Surgical treatment might contribute to prolonged survival.ConclusionThe treatment strategy of each patient should be individualized and depends on the timing of metastasis development. Selected patients with complete resection of metachronous metastases may have prolonged survival.     

Pulmonary Metastasectomy for Head and Neck Cancers

Background: Distant metastases from carcinomas that arise from the head and neck region are infrequent. The most common site is the lung. To evaluate the results of resection of pulmonary metastases for head and neck cancers, we reviewed our own cases of these metastases.Methods: Between November 1966 and March 1995, 83 patients with pulmonary metastases from head and neck cancers underwent 94 thoracic operations. All patients had obtained or had obtainable locoregional control of their primary head and neck cancers. Kaplan-Meier and Cox regression models were used to analyze the prognostic factors for survival after metastasectomy.Results: Median age was 53 years (range, 17–77). Fifty-nine were male and 24 were female. Forty-one patients had squamous cell cancers, and 36 had glandular tumors that consisted mostly of thyroid and adenoid cystic carcinomas. The median disease-free interval from the time of treatment of the head and neck primary cancers to the development of pulmonary metastases was 27 months. Sixty-eight (82%) patients had complete resection. Overall operative mortality rate was 2%. Overall actuarial survival rate after metastasectomy was 50% at 5 years. Patients with glandular tumors had a 5-year survival rate of 64% compared with 34% for patients with squamous cell cancers. When the patients with glandular tumors were analyzed according to their histology, patients with adenoid cystic carcinomas had an 84% 5-year survival, but none remained disease-free. Patients with thyroid cancers fared similarly whether they were treated medically or surgically. On multivariate analysis, the adverse prognostic factors for patients with squamous cell cancers were incomplete resection, age greater than 50 years, and disease-free interval less than or equal to 2 years.Conclusions: Approximately 30% of patients with pulmonary metastases from squamous cell cancers of the head and neck who underwent complete resection of all their metastases can expect to achieve long-term survival. The role of pulmonary resection for patients with glandular tumors is unclear.Presented in part at the 51st Annual Symposium Meeting of the Society of Surgical Oncology, San Diego, March 26–29, 1998.     

Solitary thyroid metastasis from colorectal cancer: Case report

Introduction and importanceThyroid metastasis of colorectal cancer is rare and the patient with thyroid metastasis has no symptoms early in the disease course. On the other hand, evaluation of thyroid is not generally included in the routine follow-up of colorectal cancer. Therefore, the diagnosis of thyroid metastasis of colorectal cancer may be delayed.Presentation of caseChest computed tomography revealed a nodule on the right lobe of the thyroid in 53-year-old woman diagnosed with sigmoid colon adenocarcinoma. This nodule was identified having as increased metabolic activity by ¹⁸F-fluorodeoxyglucose positron emission tomography-computed tomography and confirmed to be consisted of cystic and solid portions by ultrasonography. Fine needle aspiration cytology of the nodule revealed metastasis of colon cancer. The patient underwent laparoscopic anterior resection and a total thyroidectomy. The size of the thyroid tumor was 1.2 cm with free resection margin.DiscussionThe clinical features of thyroid metastasis from colorectal cancer are not typical. In addition, follow-up examinations of patients with colorectal cancer do not include imaging studies of the neck, so the diagnosis of thyroid metastases is delayed. The management strategies for thyroid metastasis from colorectal cancer include a total thyroidectomy without prophylactic neck lymph node dissection and chemotherapy. However, as the penetration of chemotherapeutic drugs into the thyroid is difficult, the effect on the thyroid is considered insignificant.ConclusionSurgical treatment should be considered for treatment of thyroid metastasis.     

Solitary liver metastasis from follicular variant papillary thyroid carcinoma: A case report and literature review

IntroductionPapillary (PTC) and follicular (FTC) thyroid carcinomas, together known as differentiated thyroid carcinomas (DTC), are among the most curable of cancers. Sites of metastases from FTC are usually osseous and those from PTC are in regional nodal basins and the lungs. Visceral metastases are rare and when they do occur, they tend do so in multiple sites. We present the case of a patient with a follicular variant of PTC and a solitary metastasis to the liver then review the relevant literature.Presentation of caseAn otherwise healthy 68-year-old woman was diagnosed with follicular variant papillary thyroid cancer in 2003 and subsequently underwent thyroidectomy. The patient’s endocrinologist conducted surveillance of her thyroid cancer. In 2012, due to rise in thyroglobulin, a whole body radioiodine scan was obtained which revealed an iodine-avid left liver lobe mass. Three cycles of radioiodine ablation therapy were unsuccessful and eventually the patient was referred for surgical resection. Metastatic evaluation including a PET scan was negative with the exception of an isolated enhancing 4 cm mass in segment 4B of the liver. Anatomic segmental resection of liver was performed without complications. Intraoperative ultrasonography was used to guide resection of the liver mass. Pathology reports confirmed metastatic follicular variant of PTC. Surgical margins were free of tumor. Patient was discharged home and is doing well one year after surgery. The latest thyroglobulin level was undetectable.DiscussionPost-operative surveillance by PCP, endocrinologist or surgeon for patients with thyroid carcinoma should be performed routinely. If identified, a solitary liver metastasis from primary thyroid carcinoma should be considered for surgical resection. Due to sparse data available in literature, collecting more data to establish algorithms for treatment of such rare metastatic cancers may be able to aid physicians to achieve better outcomes.ConclusionRare distant sites of metastases from DTC include eyes, pharynx, skin, muscle, ovaries, adrenal glands, kidneys, esophagus, pancreas and liver. Isolated, resectable liver metastases from PTC are exceedingly rare. Literature review revealed only 10 reported cases of liver metastases from DTC. As in our patient, solitary liver metastasis from PTC should be considered for surgical resection which offers the best chance for prolonged survival.

Correlations of neck ultrasound and pathology in cervical lymph node of papillary thyroid carcinoma

Abstract

Background: High-resolution sonography is becoming a method of choice for the detection and diagnosis of cervical lymph node metastasis in patients with papillary thyroid carcinoma (PTC). The purpose of this study is to assess the diagnostic accuracy of neck ultrasound (US) in the detection of lymph node metastases from PTC.

Methods: Data for all patients with papillary thyroid cancers and preoperative neck US were reviewed retrospectively. The diagnostic accuracy of US was determined according to whether histologically confirmed cancer was present in surgical cervical lymph node specimens.

Results: A total of 206 patients (149 central and 57 central and lateral lymph nodes dissection) were included. Their mean age was 56 years (14–88 years). Central and lateral lymph nodes were involved in 68% (n?=?141 patients; 141/206) and 60% (n?=?34 patients; 34/57) of cases, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of US in predicting papillary thyroid carcinoma (PTC) metastasis in the central neck were 69%, 71%, 84% and 51% respectively, and in the lateral neck were 85%, 65%, 78% and 75% respectively.

Conclusions: Preoperative neck US is a valuable tool in the detection of cervical lymph node metastases from papillary thyroid cancer and can provide reliable information to assist in surgical management.     

Resection of brain metastases from sarcoma

Background: Brain metastases from sarcoma are rare, and data concerning the treatment and results of therapy are sparse. Methods: We retrospectively reviewed 25 patients with brain metastases from sarcoma of skeletal or soft-tissue origin, surgically treated in a single institution during 20 years. Results: In 18 patients the brain lesion was located supratentorially, and in 7 patients infratentorially. Median age at brain metastasis diagnosis was 25 years. Median time from primary diagnosis to diagnosis of brain metastasis was 26.7 months. Lung metastases were present in 19 patients and in 8 patients they were synchronous with the brain lesion. Pulmonary metastases were resected in 12 patients (48% of total, and 63% of those with pulmonary lesions). The overall median survival from diagnosis of the primary sarcoma was 38 months and from craniotomy was 7 months. The presence or absence of lung lesions did not alter the median survival as calculated from diagnosis of brain metastasis. Overall percent survival was 40% at 1 year and 16% at 2 years. Conclusions: Because brain metastases from sarcoma are refractory to alternative treatment, surgical excision is indicated when feasible. Brain metastases from sarcoma are uncommon, usually occurring with or after lung metastasis. Long-term survival is possible in some patients.Results of this study were presented at the 47th Annual Cancer Symposium of the Society of Surgical Oncology, Houston, Texas, March 17–20, 1994.     

Mandibular metastasis revealed papillary thyroid carcinoma: Rare case

IntroductionPapillary carcinoma is the most frequent differentiated malignant thyroid neoplasm, Metastasis occurs frequently in regional lymph nodes and mandibular metastasis are very rare and most are secondary to follicular carcinomas due to their blood diffusion, The mandibular metastasis of papillary carcinoma is exceptional.Case reportWe report a rare case of mandibular metastasis revealing papillary thyroid carcinoma in a 52-year-old patient, with a review of the literature on clinical features, radiological aspect, and treatment options.Discussion conclusionMandibular metastasis of thyroid cancer are rare and the initial metastases revealing papillary carcinoma are exceptional, few cases are reported in the literature, and due to their rarities and relative lack of data on their management, There is no clearly defined processing algorithm.     

Cystic metastasis from head and neck squamous cell cancer: A distinct disease variant?

BACKGROUND: Head and neck squamous cell carcinoma (HNSCC) commonly spreads to regional deep cervical nodes. In most cases, these metastases present as firm, solid masses in the designated lymph node chains. A distinct subset of metastatic nodes present as cystic masses, with most of the volume made up of a liquid center surrounded by a thin solid rim. It has been observed that certain squamous cell carcinoma (SCC) subsites are more likely to produce metastases that are cystic. These sites predominantly include primary tumors of tonsil tissue from Waldeyer's ring. In the past, these cystic cancers often have been erroneously diagnosed as branchiogenic carcinomas, that is, a branchial cleft cyst that has undergone malignant degeneration. Today, most authors have concluded that so-called branchiogenic carcinomas are actually cystic metastases in the neck probably arising from an oropharyngeal primary SCC. The purpose of this work is to consider the phenomenon of cystic lymph node metastasis in head and neck cancer in depth. METHODS: A review of the relevant English-language literature linking cystic metastasis and head and neck cancer was performed. RESULTS: These studies indicate that lateral cystic masses in adults often represent an occult primary cancer originating in the epithelium within Waldeyer's ring. CONCLUSIONS: Adult patients who are initially seen with a lateral cystic neck mass must be presumed to have a cancer until proven otherwise. The mass should be biopsied by fine-needle aspiration (FNA). However, negative FNA findings may be misleading; therefore, an excisional biopsy and examination under anesthesia with directed biopsies of Waldeyer's ring and bilateral tonsillectomy should be considered a part of the diagnostic workup.     

A single thyroid nodule revealing early metastases from clear cell renal carcinoma: case report and review of literature

IntroductionWe report the case of an incidental solitary renal cancer cell (RCC) thyroid metastatic nodule treated by thyroidectomy.Presentation of caseA 53 year male presented with a solitary, asymptomatic thyroid nodule. He was treated with left nephrectomy 1 year before for a RCC. Radiological standard follow-up was negative for secondary lesions but ultrasound (US) 12 months after surgery revealed a 1.5 cm solid nodule in the right lobe of the gland. Fine needle aspiration biopsy (FNAB) was inadequate and the patient was submitted to total thyroidectomy. Histology showed the presence of solitary metastasis from RCC. At 2 years follow-up, no evidence of recurrence has been found.DiscussionSolitary RCC metastasis to the thyroid usually occurs late from nephrectomy and have no specific US pattern. When FNAB provides an uncertain cytological results, the patient received thyroidectomy for primary thyroid tumors and diagnosis of metastases from RCC was incidentally made.ConclusionThyroid nodules in a patient with history of malignancy can pose a diagnostic challenge. The presence of a solitary thyroid nodule in a patient with history of RCC should be carefully suspected for metastasis. We suggest to extend at neck the thorax and abdomen CT scan routinely recommended during the follow-up in high-risk cases. Thyroidectomy may result in prolonged survival in selected cases of isolated thyroid metastasis from RCC.     

First case of huge classic papillary thyroid cancer rupturing spontaneously leading to ischemic necrosis,perforation and inflammation of overlying skin: Case report and review of the literature

IntroductionPapillary thyroid cancer (PTC) is the commonest form of well-differentiated endocrine carcinoma. It is categorized into indolent and aggressive, where the indolent subtypes (classic, follicular) rarely demonstrate aggressive behavior. We present a classic PTC presenting with a rapidly growing huge anterior neck mass that subsequently spontaneously ruptured subcutaneously resulting in ischemia, necrosis, and perforation of overlying skin leading to inflammation.Presentation of caseA 37-year-old female with no comorbidities presented to our emergency department with a neck swelling of 2 years duration that rapidly enlarged one week prior to presentation. Though the mass initially appeared of inflammatory nature, the tumor was a PTC, and she underwent total thyroidectomy with selective right side neck dissection and debridement of necrotic skin. The gross specimen revealed a fragmented non-intact right thyroid lobe mass causing pressure ischemia, necrosis and perforation of the skin. Histopathology showed a 9 × 9 × 5 cm classic PTC staged as pT3b N1b. Postoperative course was uneventful, she was discharged by the eighth postoperative day, and then she received a high dose of radioactive iodine ablation (RAI).DiscussionClassic PTC is usually of a smaller size and a relatively benign course compared to other PTC subtypes and thyroid cancers. It is indolent with favorable prognosis. Although it is associated with increased risk of lymph node metastases at the time of diagnosis, it is slow growing with high survival rates approaching 95%.ConclusionDespite that classic PTC progresses slowly, it should still be suspected in neck swellings presenting with rapid and aggressive behavior. Prompt and systematic assessment is required with surgical intervention and radioactive iodine ablation therapy.     

Colorectal carcinoma and brain metastasis: Distribution,treatment, and survival

Background: Brain metastasis from colorectal cancer is rare. The present study reports the nature of this disease and analyzes factors correlated with survival in patients harboring such disease. Patients and Methods: One hundred patients diagnosed between 1980 and 1994 with metastatic brain tumors secondary to colorectal adenocarcinoma were retrospectively reviewed. Of these patients, 36 underwent surgery, 57 underwent radiotherapy alone, and the remaining seven received steroids. Results: The most common primary sites were the sigmoid colon and rectum (65%). Brain metastases with concomitant liver and/or lung metastases were seen more frequently than brain metastases alone. The median interval between the diagnosis of primary cancer and the diagnosis of brain metastasis was 26 months (95% confidence interval =22–30). The median survival time after the diagnosis of brain metastasis was 1 month for patients who received only steroids, 3 months for those who received radiotherapy (p=0.1), and 9 months for those who underwent surgery (p<0.0001). The extent of noncerebral systemic disease was not correlated with survival (p>0.05), but early onset of brain metastasis was significantly associated with poor prognosis (p=0.04). Conclusion: Surgical removal of colorectal metastatic brain lesions results in significantly increased survival time, regardless of the status of the noncerebral systemic disease.     

Parapharyngeal lymph node metastasis: an unusual presentation of papillary thyroid carcinoma

BACKGROUND: Parapharyngeal space nodal metastases are usually secondary to malignancies of the pharynx and sinonasal tract, although localization of lymphomas is also possible. Parapharyngeal metastases arising from thyroid papillary carcinoma are instead an exceedingly rare event, with only 10 cases reported up to now in the literature. METHODS: We describe two cases of parapharyngeal metastasis from thyroid papillary carcinoma in a man and a woman, aged 40 and 52 years, respectively. RESULTS: Both patients had a lesion that clinically appeared to be located in the parapharyngeal space; they underwent CT and MRI, which detected a cystic mass in the poststyloid compartment. In the first patient, fine-needle aspiration cytology failed in identifying the histologic nature of the lesion, which was excised through a transcervical approach. A diagnosis of metastatic thyroid papillary carcinoma was rendered and therefore the patient underwent total thyroidectomy. In the second patient, a total thyroidectomy, previously scheduled for multinodular goiter, was performed along with the removal of the parapharyngeal mass. Definitive histologic findings revealed that the two parapharyngeal masses were cystic metastases from a thyroid papillary carcinoma. Both patients received postoperative 131I treatment. Twenty-four months after surgery, the first patient is free of disease, whereas the second one has clear signs of abnormal 131I uptake in the lungs. CONCLUSIONS: The differential diagnosis of a parapharyngeal poststyloid mass should also include metastasis from thyroid papillary carcinoma. When the lesion displays a cystic appearance on imaging, it is advisable to rule out a thyroid primary by ultrasonographic examination. The occurrence of a metastasis in such unusual site, even though rarely reported, does not seem to significantly affect the prognosis of the disease.     

Prognostic evaluation of intracranial metastasis in malignant melanoma

Background: Malignant melanoma (MM) is often reported as the third most common cause of intracranial metastasis (IM) after carcinoma of the breast and lung. Most patients with advanced MM will have widespread extracranial disease, but the majority will die from intracerebral spread. Methods: A retrospective review of 117 patients with documented IM from MM over the past 25 years was undertaken. Various factors (including age, race, sex distribution, primary lesions with Clark's level, Breslow's thickness, primary sites and staging at initial presentation, diagnosis of IM and its various treatment methods, survival data, and autopsy findings) were analyzed. Prognostic indicators were clarified from this analysis as a predictor of central nervous system (CNS) metastasis. An ideal treatment plan was also analyzed in order to predict a better survival. Results: Fifty-eight percent of patients were male; 42% were female. Seventy-one percent of the primary lesions were of Clark's level IV and V, with mean Breslow's thickness of 3.5 mm. Median time interval between the initial diagnosis and development of IM was 3.5 years. Complete surgical resection of the intracranial lesion in the brain resulted in the longest mean survival of 10.3 months, whereas mean survival for the group with no treatment was only 3 weeks. Patients with primary lesions of the head and neck had the lowest mean survival of 3.3 months, whereas those whose primary sites were unknown had the longest mean survival of 7.5 months. One- and 2-year survival were 9% and 3%, respectively. All but one of the 30 patients at autopsy were found to have visceral metastasis, namely of the lung, liver, and bone. Conclusion: An aggressive search for metastasis should be undertaken in patients at high risk of developing CNS metastasis, e.g., male, head and neck primary, Clark's level IV and V, Breslow's thickness of >3 mm, and presence of visceral metastases, mainly lung. A complete surgical resection should be attempted whenever possible, with adjunctive use of whole-brain irradiation, along with systemic chemotherapy for further control of recurrence and to prolong survival.Presented at the 46th Annual Cancer Symposium of the Society of Surgical Oncology, Los Angeles, March 18–21, 1993.     

Lymph node metastasis between the sternocleidomastoid and sternohyoid muscle in papillary thyroid carcinoma patients: A prospective study at multiple centers

BackgroundThe lymph nodes between the sternocleidomastoid and sternohyoid muscle (LNSS) are not explicitly mentioned in the 2015 American Thyroid Association and 2008 American Head and Neck Society (AHNS) guidelines, but they are easily overlooked in papillary thyroid carcinoma (PTC). We prospectively evaluated the clinical significance of the LNSS in papillary thyroid carcinoma (PTC) patients.MethodIn five medical centers, two hundred and thirty-four PTC patients with lateral neck metastasis who underwent 264 neck dissection were enrolled in this study. LNSS was resected and used as a specimen to investigate the relationship of LNSS with several clinicopathological parameters.ResultOf the 264 lateral neck dissections, the average lymph node metastasis rate of LNSS was 23.48%, significantly second only to that in level III (p<0.05). Univariate and multivariate analyses showed that a patient age over 45 years (OR 2.155, 95% CI 1.191 to 3.898, p = 0.011), with a tumor located in the inferior lobe of the thyroid (OR 1.517, 95% CI 1.113 to 2.068, p = 0.008), and LN metastasis at levels IIb (OR 2.298, 95% CI 1.121 to 4.712, p = 0.020) and level III (OR 2.408, 95% CI 1.222 to 4.745, p = 0.011) were independent risk factors for LNSS lymphatic metastasis.ConclusionThe LNSS has a high metastatic rate and is easily overlooked. Additional attention should be paid to LNSS, especially in patients over 45 years old and with PTC located in the thyroid’s inferior lobe.     

An early orbital metastasis from breast cancer: A case report

IntroductionOrbital metastases from solid cancers are infrequent or underestimated, since they represent only 1–13% of tumors of the orbit. They are even less frequent in breast cancer and are rarely diagnosed. We report a case of an early diagnosed orbital metastasis from breast cancer to an extra ocular muscle.Case reportWe report the case of a 33-year-old female patient who presented, following the diagnosis of her breast cancer, headache, a progressive decrease in visual acuity of the right eye and diplopia. Brain imaging revealed a tissue process at the expense of the internal rectus muscle, which biopsy pointed to a secondary lesion of breast cancer.DiscussionExtraocular muscles are rarely infiltrated by metastasis from distant sites. They are mostly asymptomatic and suggest a systematic spread of the disease. The treatment is generally palliative and the prognosis is generally poor.ConclusionOrbital metastases from breast cancer are certainly rare but are associated with significant morbidity. In order to make a precise diagnosis and offer an appropriate treatment, healthcare professionals must remain vigilant in the face of any ophthalmological symptoms.

Cutaneous metastasis revealing a relapse of gastric linitis: Another case

INTRODUCTIONCutaneous metastasis from gastric cancer is a rare occurrence. The linitis gastric carcinoma accounts only 8.7% of all gastric cancers.PRESENTATION OF CASEWe report a case of female patient who was followed for linits cancer with peritoneal metastasis treated by six cycles of chemotherapy. After seventeen months of control, the relapse of the disease revealed by occurrence of cutaneous metastatsis.DISCUSSIONCutaneous metastasis from linit gastric is rare and the prognostic remains poor. The treatment is palliative.CONCLUSIONThis rare presentation should encourage the practitioners to biopsy any suspicion skin lesion.
