Outcomes of Cancer Surgery During the COVID-19 Pandemic: Preparedness to Practising Continuous Cancer Care.

The COVID-19 pandemic has placed unprecedented pressure on healthcare services. Deprioritisation of nonemergency clinical services and growing concerns of adverse outcomes of COVID-19 in cancer patients is having a deleterious impact across oncologic practice. We report cancer surgery outcomes taking into account the acuity of the COVID-19 situation. A prospectively maintained database of the Department of Surgical Oncology was analysed from 1st May to 30th June, 2020, to evaluate the perioperative outcomes, morbidity and mortality following major surgical procedures. A total of 359, preoperatively, tested negative for COVID-19 underwent surgery. Median age was 52 years with 26.7% (n = 96) above the age of 60 years. Sixty-one percent (n = 219) patients were American Society of Anaesthesiology grades II-III. As per surgical complexity grading, 36.8% (n = 132) cases were lower grades (I-III) and 63.2% (n = 227) were complex surgeries (IV-VI). 5.3% (n = 19) had ≥ grade III Clavien-Dindo complication, and the postoperative mortality rate was 0.27% (n = 1). Major complication rates in patients > 60 years were 9.3% in comparison to 4.1% in < 60 years (p = 0·63). The median hospital stay was 1-10 days across subspecialties. Postoperatively, repeat COVID 19 testing in 2 suspected patients were negative. Our study showed that after screening, triaging and prioritisation, asymptomatic cases may undergo cancer surgeries without increased morbidity during COVID-19 pandemic.

Primary Hyperparathyroidism: Is Image Localization Alone Sufficient to Ensure Long-Term Cure in Unifocal Disease?

INTRODUCTION: Advances in imaging have facilitated precise preoperative localization and focused resection of hyperfunctional parathyroids in primary hyperparathyroidism (PHPT). Combining imaging techniques or a "dual" approach, when concordant, improves adenoma-localizing accuracy above individual modalities. This study sought to assess biochemical cure and failure rates (persistence or recurrence) of surgery directed by dual imaging alone in PHPT. METHODOLOGY: This observational, single-center analysis comprised 31 patients diagnosed with PHPT and imaged with both ultrasound (USG) of the neck and sestamibi scintigraphy. The extent of surgery was based solely on inter-modality concurrence for adenoma localization; imaging-concordant patients underwent focused parathyroidectomy, whereas discordant patients necessitated neck exploration (with extent altered according to scintigraphic lesion lateralization). No intraoperative localizing adjuncts were used. RESULTS: Twenty-three patients had concordant imaging, of which 19 underwent focused exploration, with sensitivity and positive predictive value (PPV) for dual imaging of 100% and 95.7%, respectively. The overall sensitivity and PPV were 92.9% and 89.7% for USG alone and 100% and 93.6% for scintigraphy, respectively. The mean age and prevalence of thyroid disease were significantly higher in the discordant group. All patients achieved postoperative normocalcemia. There were no cases of persistent or recurrent hyperparathyroidism on follow-up. CONCLUSIONS: In the imaging-concordant setting, focused surgery may be safely performed with the omission of other adjuncts for localization. Older age and concomitant thyroid pathology predispose to discordant imaging and are risk factors for surgical failure when attempting an image-directed approach. Neck exploration is an alternative in these patients with excellent cure rates and acceptable morbidity.

Salvage Surgery in Recurrent Oral Squamous Cell Carcinoma.

More than half of patients with oral cancer recur even after multimodality treatment and recurrent oral cancers carry a poorer prognosis when compared to other sites of head and neck. The best survival outcome in a recurrent setting is achieved by salvage surgery; however, objective criteria to select an ideal candidate for salvage surgery is difficult to frame, as the outcome depends on various treatment-, tumor-, and patient-related factors. The following is summarizes various tumor- and treatment-related factors that guide our decision-making to optimize oncologic and functional outcomes in surgical salvage for recurrent oral cancers. Short disease-free interval, advanced tumor stage (recurrent and primary), extracapsular spread and positive tumor margins in a recurrent tumor, regional recurrence, and multimodality treatment of primary tumor all portend worse outcomes after surgical salvage. Quality of life after surgical intervention has shown improvement over 1 year with a drastic drop in pain scores. Various trials are underway evaluating the combination of immunotherapy and surgical salvage in recurrent head and neck tumors, including oral cavity, which may widen our indications for salvage surgery with improved survival and preserved organ function.

Thyroid Hemiagenesis and Papillary Carcinoma: a Rare Association.

A 20-year-old female presented with a slowly growing solitary left thyroid nodule for 1 year. USG and CECT neck showed a 4 × 3 cm solid-cystic nodule in the left lobe of thyroid, with notable absence of the right lobe. FNAC from the nodule was Bethesda V. Operative findings confirmed right thyroid lobe agenesis with corresponding absence of right superior thyroid vessels. The right sided RLN, ESBLN, superior and inferior parathyroids, and inferior thyroid vasculature were in their anatomical positions. She underwent standard left hemithyroidectomy. Histopathological examination revealed follicular variant of papillary carcinoma.

Amalgamation of Central Lymph Node Dissection in Papillary Thyroid Carcinoma: Study from South Indian Population.

The aim of this study was to evaluate the correlation between central lymph node (CLN) metastasis and Clinicopathological characteristics of papillary thyroid cancer (PTC). In addition, we investigated the incidence and risk factors for ipsilateral and contra lateral CLN metastasis in unilateral PTC and the appropriate surgical extent for CLN dissection. A prospective study of 143 patients with unilateral PTC who underwent total thyroidectomy and prophylactic bilateral CLN dissection was conducted. Of 143 patients, 58 had CLN metastases. The rate of CLN metastasis was considerably higher in cases of maximal tumor size > 1 cm (P < 0.0001; OR 5.81). Ipsilateral CLN metastasis was detected in 41% of cases of unilateral PTC, and contra lateral CLN metastases was found in 14% of cases where as bilateral CLN metastases in 8% of cases. The rate of contra lateral CLN metastasis was considerably higher in cases of PTC with a large tumor size (≥ 1 cm) (P = 0.0003; OR = 0.144) and with ipsilateral CLN metastasis (P = 0.0002; OR 0.12). Tumor size > 1 cm was independent risk factors for CLN metastasis. Maximal tumor size > 1 cm and presence of ipsilateral CLN macro metastasis were independent risk factors for contra lateral CLN metastasis. Therefore, both ipsilateral and contra lateral CLN dissections should be considered for unilateral PTC with a maximal tumor size > 1 cm or presence of ipsilateral CLN macro metastasis.

Recurrent Bleeding Neck Mass: a Case Report.

An adult male presented to us with a recurrent, large bleeding tumour in the neck. We describe our approach to the patient, whose tumour was labelled as an atypical glomus on final histopathology. They are relatively uncommon in the head neck, and this case report with literature review is expected to add to our knowledge.

Xeroderma pigmentosum: clinicopathological review of the multiple oculocutaneous malignancies and complications.

Multiple oculo-cutaneous malignancies are a common manifestation on sun-exposed facial areas in patients with Xeroderma pigmentosum (XP). Commonly seen are the basal cell carcinoma and the squamous cell carcinomas which manifest in the early first decade in contrast to fifth and sixth decade in the general population. XP manifests as photosensitivity, hyperpigmentation, premature skin aging and malignant changes like squamous cell carcinoma, basal cell carcinoma, fibrosarcoma and rarely malignant melanoma as well as internal malignancies. We report 11 cases of Xeroderma pigmentosa managed in our institute which included sex males and five females. All had photosensitivity, hyperpigmentation and consanguinity with facial malignant lesions like SCC and BCC. Ocular signs of photophobia and excessive lacrimation was seen in all the cases while blurring of vision due to corneal clouding, corneal injection, pterygium and limbal SCC were seen in 5 cases. SCC of the lids were seen in 7 cases while BCC seen in 8 cases and limbal and conjunctival SCC seen in one case. All were managed with excision while one case of melanoma with neck secondaries needed radical neck dissection while the other orbital exenteration. Oculo-cutaneous malignancies occur in the sun exposed areas so patients are advised regular follow up with speciality care. Awareness about the rare condition and importance of early detection and prevention of UV rays induced skin damage should be propagated. The disease is ultimately fatal, life can be prolonged by simple preventive measures to minimize sun exposure and early detection of the skin lesions and management.

Chondroradionecrosis of larynx a delayed complication of radiotherapy: management and review of literature.

UNLABELLED: Background/objectives Chondroradionecrosis (CRN) of the larynx is a rare and grave complication of radiotherapy which can be fatal if not managed aggressively. A recent trend towards organ preservation protocols towards even advanced stage laryngeal malignancies and with further advances in terms of technology and safety radiation as external beam and intensity modulated varieties are preferred for certain stages of squamous cell carcinomas. Materials and methods We are reporting a series of 4 cases of CRN of the larynx treated in our hospital with 3 cases of stage III carcinoma glottis and one stage III carcinoma supraglottis with no nodal metastasis. One glottis cancer had 2 sittings of laser microlaryngeal excision earlier. All were in grade 4 CRN and one improved with medical line and HBO and the other 3 progressed and salvage laryngectomy and pectoralis major myocutaneous flap to cover the fistulous skin defect was grafted. CONCLUSION: Laryngeal CRN being a rare and intensely morbid complication of radiotherapy should be suspected and diagnosed at the earliest by endoscopic and imaging methods. Disease progression and chances of tumor recurrence should be followed up with PET CT and a call on salvage laryngectomy with repair of the anterior neck defects with non irradiated musculocutaneous flaps or vascularised tissue transfer should be promptly taken.

Supraclavicular artery flap for head and neck oncologic reconstruction: an emerging alternative.

AIM: Head and Neck oncologic resections often leave complex defects which are challenging to reconstruct. The need of the hour is a versatile flap which has the advantages of both a regional flap (viz. reliable and easy to harvest) and a free flap (thin, pliable with good colour match). In this a study we assessed the usefulness of the supraclavicular artery flap in head and neck oncologic defects. MATERIALS AND METHOD: The flap was used as a pedicled fasciocutanous and was based on the transverse supraclavicular artery. We assessed this reconstructive option for complications as well as its and functional out comes. RESULTS: Eleven cases underwent supraclavicular artery flap between 20011-2012 of which 5 were males and 6 females. Mean defect size was 5 cm × 6 cm. Nine donor sites were closed primarily and 1 required split skin grafting. We encountered one complete flap loss which was attributed to a band of constricting skin bridge over the vascular pedicle in a defect involving lateral third of midface. Two patient developed pharyngeocutaneous fistula (without flap loss) out of 3 patients who underwent augmentation pharyngoplasty post Near total laryngectomy. CONCLUSION: Supra clavicular artery flap is a thin versatile, reliable, easy to harvest, with good cosmetic and functional outcome at both ends (recipient and donor) for reconstructing head and neck oncologic defects.

Paragangliomas of the carotid body: current management protocols and review of literature.

Paraganglioma is a rare neoplasm arising from carotid body usually benign and constitute 0.5 % of all total body tumors. They constitute 60-70 % of head and neck paraganglioma and resemble other paragangliomas of the body like glomus jugulare, glomus tympanicum, and pheochromocytoma. This is a retrospective analysis of the medical records of carotid body paraganglioma cases. Nine patients operated during the study period and the follow up traced were included in the study. Seven females and 2 males were analysed. Six had tumor on the left side and 3 had on the right side. All the cases surgical excision was done by a tranverse incision as 2 patients had Shamblin I, 5 patients had Shamblin II, and 1 patients Shamblin IIIa. All the Shamblin I had tumor away from the carotids and were easily dissected without vessel damage, a sub adventitial tumor excision was performed in all the 5 cases of Shamblin II, 1 case of Shamblin IIIa was dissected with difficulty without sacrificing or vessel reconstruction. Paraganglioma of the carotid body should be considered as a differential diagnosis for painless lateral neck masses. Larger tumors need a multidisciplinary team of head and neck with vascular surgeons for better results.

Cutaneous malignancies in xeroderma pigmentosum: earlier management improves survival.

Xeroderma pigmentosum (XP) is a rare autosomal recessive disease, characterized by hypersensitivity of the skin to ultraviolet (UV) radiation leading to high incidence of skin cancer and progressive neurological complications. It results in premature development of neoplasias due to an exacerbated hypersensitivity to UV radiation causing premalignant and malignant lesions leading to death in early adulthood. Two cases of clinical features of xeroderma pigmentosa with skin lesions were managed in our department. One had multiple clusters of basal and squamous cell carcinomas and the other had malignant melanomas and right neck nodes. Both were treated with multiple wide excisions and the neck node were surgically managed with radical neck dissections. Skin malignancies were common in the sun exposed areas and patients were advised regular 3 months follow up. The disease is ultimately fatal, life can be prolonged by simple preventive measures to minimize sun exposure. Comprehensive multimodality management includes patient education and counselling for the psychosomatic disorder and genetic counseling remains the most important preventive measure.

Neck dissection followed by definitive radiotherapy for small upper aerodigestive tract squamous cell carcinoma, with advanced neck disease: an alternative treatment strategy.

Treatment options for patients with small upper aerodigestive tracts squamous cell carcinoma (T1, T2) with advanced neck disease (N2, N3) is a topic that generates controversy in terms of thereuptic stratagies. We present the retrospective analysis of 109 patients treated, between 1991 and 2008, by "Neck dissection first approach" for N2, N3 neck node, followed by external beam radiotherapy (RT) with or without chemotherapy for the operated neck and the primary, deemed radiocurable. 94 patients completed the planned treatment and formed the material for this study. The primary (tumor) stage was as follows: T1 (29) and T2 (65) commonly arising from oropharynx; the neck nodes were predominantly N2a (n = 54), followed by N2b (n = 26) and N3 (n = 14) disease. Complete nodal clearence was achieved in 89 patients, with no major post operative complications. With a median follow up of 24 months disease free survival of 70% and overall survival of 61% at 5 years. Recurrence at primary site was noted predominantly with pyriform fossa tumors (n = 8), followed by base of tongue (n = 5) and were T2 lesions. Failure in the neck was seen in predominantly N3 nodes, R1 resection and failure to comply with adjuvant treatment. Neck dissection first approach is a valid treatment option that allows a good control of the disease in the neck, where it often fails if only RT is administered, along with preserving the pharyngolaryngeal function. Care should be excercised so that there should be no delay in initiating the RT following surgery.
