P2.02-005 - A Rare Clinical Presentation Of EGFR-Mutant Non-Small Cell Lung Cancer With Oligo-Acrometastasis (ID 5278)
14:30 - 14:30 | Author(s): Y. Ağaçkıran
- Abstract
Background:
44% of acrometastasis are originated from primary lung tumors and metastasis to digits is seen in 0.2% of patients with lung cancer. After clinical staging, amputation or radiotherapy are most often therapeutic options for pain palliation. We want to present an oligo-acrometastasis of fourth proximal phalanx of left hand from EGFR-mutant non-small cell lung cancer.
Methods:
A 58-year-old man was admitted with pain and swelling in fourth finger of his left hand (Figure 1A). Magnetic resonance imaging (MRI) of left upper extremity showed a destruction by a soft tissue measuring about 30x17 mm on the distal part of fourth proximal phalanx of left hand (Figure 1B-C). Three phase bone scan with technetium-99m methylene diphosphonate (MDP) revealed increased radiotracer uptake in the fourth finger. Diffuse increased uptake is seen at the left wrist secondary to the old fracture and trauma in both blood pool and metabolic phases and hypertrophic osteoartropathy in both tibia (Figure1E-F). Computed thorax tomography (CTT) revealed a 25x21 mm lobulated contour lesion in the posterior segment of right lower lobe (Figure 1H). CT-guided biopsy was performed and pathological examination showed non-small cell lung carcinoma-not otherwise specified (NSCLC-NOS). A 24x27x24 mm mass with SUV-max value 9.85 in the right lower lobe, right tracheobronchial and right hilar lymphadenopathies 13 mm in diameter was detected (SUV-max: 7.51) on PET-CT. Patient was staged as T1bN2M1b with oligoacrometastasis. Figure 1
Results:
His finger was amputated from metacarpophalangeal level and surgery margin was negative for tumour. Pathological diagnosis was metastatic NSCLC-NOS harbouring EGFR-21L858R mutation. After curative treatment of acrometastasis, concurrent chemo-radiotherapy was planned for primary lung cancer as a therapeutic approach. He is still under treatment.
Conclusion:
Oligometastatic disease by acral involvement in NSCLC is extremely rare. Curative treatment approach should be consider for both primary tumour and metastasis side.
